00:00:13,530 --> 00:00:18,610
Welcome to episode 137 of the 
London History Podcast, where we

2
00:00:18,610 --> 00:00:21,530
share the stories of people, 
places, and events that have 

3
00:00:21,530 --> 00:00:27,250
shaped our capital. 
I am Hazel Baker, CEO of London 

4
00:00:27,250 --> 00:00:32,800
guidedwalks.co.uk. 
Today we are travelling beneath 

5
00:00:32,800 --> 00:00:37,760
the surface, quite literally, 
into a story of extraordinary 

6
00:00:37,760 --> 00:00:42,120
ambition, innovation and 
engineering genius. 

7
00:00:43,000 --> 00:00:47,240
Imagine Victorian London, the 
River Thames teeming with ships,

8
00:00:47,240 --> 00:00:53,160
and beneath it, a bold and 
unprecedented idea to dig the 

9
00:00:53,160 --> 00:00:57,400
world's first tunnel under a 
river. 

10
00:00:58,320 --> 00:01:02,320
This was no fantasy, but the 
work of a remarkable father and 

11
00:01:02,320 --> 00:01:07,440
son team, Mark Isimbard Brunel 
and his son Isimbard Kingdom 

12
00:01:07,440 --> 00:01:10,760
Brunel. 
Our guest today is Catherine 

13
00:01:10,760 --> 00:01:14,600
McAlpine and she's the director 
of the Brunel Museum, which 

14
00:01:14,600 --> 00:01:18,280
stands on the very site where 
this groundbreaking project took

15
00:01:18,280 --> 00:01:21,480
shape. 
Many know that Isabel Kingdom 

16
00:01:21,480 --> 00:01:25,080
Brunel was voted the second 
greatest Britain of all time in 

17
00:01:25,080 --> 00:01:28,360
2006, just behind Winston 
Churchill. 

18
00:01:28,920 --> 00:01:33,800
But fewer realised that his 
father, Mark Brunel, the true 

19
00:01:33,800 --> 00:01:37,080
architect of the Thames Tunnel, 
was French. 

20
00:01:37,720 --> 00:01:41,160
Forced to flee his homeland 
during the Revolution, he made 

21
00:01:41,160 --> 00:01:44,920
his way to New York before 
ultimately finding fame and 

22
00:01:44,920 --> 00:01:49,600
fortune here in Britain. 
Will return to that remarkable 

23
00:01:49,600 --> 00:01:53,040
journey in a moment. 
Catherine, welcome. 

24
00:01:53,520 --> 00:01:55,400
It's a real pleasure to have you
with us. 

25
00:01:55,400 --> 00:01:58,280
Thanks. 
For having me, I'm excited to be

26
00:01:58,280 --> 00:02:01,680
here. 
Now we've got a lot of things 

27
00:02:01,680 --> 00:02:05,480
that we need to cover today to 
absolutely jam pack it in, but 

28
00:02:05,480 --> 00:02:09,240
with focus on 1st. 
I think the Thames Tunnel in 

29
00:02:09,240 --> 00:02:12,160
itself, some people may have 
never even heard of it. 

30
00:02:12,160 --> 00:02:17,040
So what is it? 
So the Thames Tunnel was the 

31
00:02:17,040 --> 00:02:21,400
very first tunnel under a river 
anywhere in the world and we 

32
00:02:21,400 --> 00:02:24,400
take for granted now taking if 
you live in London, you're used 

33
00:02:24,400 --> 00:02:28,240
to ping ponging from north-south
under the river using the 

34
00:02:28,240 --> 00:02:30,800
Underground. 
But actually 200 years ago in 

35
00:02:30,800 --> 00:02:33,920
1825, that was a complete 
novelty. 

36
00:02:34,160 --> 00:02:37,680
People have tried to dig under 
the Thames to connect North and 

37
00:02:37,680 --> 00:02:41,320
South and had failed. 
Unfortunately it hadn't worked. 

38
00:02:41,600 --> 00:02:45,320
So that's why the 10 panelists 
exciting and important because 

39
00:02:45,320 --> 00:02:48,080
it was the world's first and we 
we take it for granted now. 

40
00:02:48,960 --> 00:02:53,560
But actually there was no 
guarantee of success in 1825 

41
00:02:53,560 --> 00:02:58,480
that this tunnel would succeed, 
let alone it surviving 200 years

42
00:02:58,480 --> 00:03:03,560
later. 
Amazing, how long is the tunnel?

43
00:03:05,600 --> 00:03:09,840
Oh, it's not very long at all in
terms of distance, in terms of 

44
00:03:09,840 --> 00:03:12,840
time. 
And to construct it, it took 

45
00:03:12,880 --> 00:03:16,960
them 18 years, which was quite 
significantly longer than the 

46
00:03:16,960 --> 00:03:20,760
three years that they had 
estimated because with no one 

47
00:03:20,760 --> 00:03:23,200
having done it before, they sort
of, you know, it was a great 

48
00:03:23,200 --> 00:03:25,000
sort of finger in the air. 
Yeah. 

49
00:03:25,040 --> 00:03:28,280
Three years, yeah, but ended up 
taking 18 to build and. 

50
00:03:28,480 --> 00:03:31,160
Why did they choose that 
particular location then from 

51
00:03:31,160 --> 00:03:33,640
Wapping to rather Hive? 
What was in it there? 

52
00:03:35,040 --> 00:03:37,600
Couple of reasons. 
One of the really important 

53
00:03:37,600 --> 00:03:40,520
reasons is to do with the 
original purpose of the tunnel, 

54
00:03:40,720 --> 00:03:44,360
which was to carry cargo from 
one side of the river to the 

55
00:03:44,360 --> 00:03:46,240
other. 
Rather high than whopping at 

56
00:03:46,240 --> 00:03:50,520
that time was really important, 
kind of dot, lots of cargo 

57
00:03:50,520 --> 00:03:55,480
coming in from across the world 
across the Empire coming into 

58
00:03:55,480 --> 00:03:59,160
London, which was a huge port 
city and the only way at that 

59
00:03:59,160 --> 00:04:03,680
point of crossing from north to 
South, the furthest east was 

60
00:04:03,680 --> 00:04:05,560
London Bridge. 
There were plenty of bridges 

61
00:04:05,560 --> 00:04:08,920
further up the river to the 
West, but the most easterly 

62
00:04:08,920 --> 00:04:12,480
bridge was London Bridge. 
It would take a really long time

63
00:04:12,560 --> 00:04:15,560
to get through traffic and 
nothing ever changes but to take

64
00:04:15,560 --> 00:04:20,240
things by load over the bridge, 
who could be a long time. 

65
00:04:20,480 --> 00:04:23,280
And if you couldn't move your 
cargo, you had to run the ship 

66
00:04:23,280 --> 00:04:27,960
through in the warehouses, which
meant that it's much more to be 

67
00:04:27,960 --> 00:04:31,120
susceptible to high risky and. 
Shrinkage. 

68
00:04:31,360 --> 00:04:33,720
I think we call. 
It it's shrinking sprinkles 

69
00:04:33,760 --> 00:04:38,480
exactly that that fantastic. 
So that was a real issue with 

70
00:04:38,480 --> 00:04:43,280
sort of trying to get cargo from
one side to put it in the dark, 

71
00:04:43,280 --> 00:04:44,640
make it as convenient as 
possible. 

72
00:04:44,760 --> 00:04:48,520
The other reason is geology. 
And so one of the things that 

73
00:04:48,520 --> 00:04:51,400
was really clever about the way 
that Mark Brunel designed the 

74
00:04:51,400 --> 00:04:55,320
digging of the tunnel was he 
used the soft earth rocket hive 

75
00:04:55,440 --> 00:04:59,960
to his advantage. 
They thunk and shaft into the 

76
00:04:59,960 --> 00:05:04,600
ground and instead of digging, 
they built it onto the ground 

77
00:05:05,200 --> 00:05:09,040
and let it think. 
So having that sort of accurate 

78
00:05:09,040 --> 00:05:12,840
geology meant that they could 
supposedly meant that it would 

79
00:05:12,840 --> 00:05:17,520
be easier to dig this tunnel. 
So the location was one reason 

80
00:05:17,520 --> 00:05:19,040
and then the sort of geology the
other. 

81
00:05:20,800 --> 00:05:23,240
And of course, this is going to 
be saving a lot of money, let 

82
00:05:23,240 --> 00:05:26,400
alone the shrinkage. 
But of course, keeping anything 

83
00:05:26,400 --> 00:05:29,760
in a warehouse rather than 
getting that product to market, 

84
00:05:29,840 --> 00:05:32,120
it's going to cost money by just
sitting there. 

85
00:05:32,120 --> 00:05:35,960
So moving it as soon as you can 
was an advantage, which means 

86
00:05:36,280 --> 00:05:40,000
they are saving money. 
So who was putting in the money 

87
00:05:40,720 --> 00:05:44,640
to build this tunnel? 
So it was definitely intended as

88
00:05:44,640 --> 00:05:47,320
a commercial enterprise. 
It was meant to be this sort of 

89
00:05:47,320 --> 00:05:51,440
toll tolled Rd. between the sort
of the dock that you could move 

90
00:05:51,440 --> 00:05:54,040
your cargo and you'd get lots of
income from that. 

91
00:05:54,040 --> 00:05:58,360
So lots of people saw the value 
of this from when Mark Brunel 

92
00:05:58,360 --> 00:06:01,280
patented this cunning shield in 
1818. 

93
00:06:01,480 --> 00:06:06,040
In 1824, he gave a lecture to 
the Institute of Civil Engineers

94
00:06:06,040 --> 00:06:09,200
about this fantastic idea that 
he's had, and he got all these 

95
00:06:09,200 --> 00:06:14,320
sorts of entrepreneurs, prime 
individuals, to invest in what 

96
00:06:14,320 --> 00:06:16,440
became the Thames Tunnel 
Company. 

97
00:06:16,440 --> 00:06:19,840
So that's how they got their 
original funding. 

98
00:06:20,160 --> 00:06:23,480
But unfortunately, because it 
was the first time they'd ever 

99
00:06:23,480 --> 00:06:26,840
done it, it was not the most 
kind of plain sailing 

100
00:06:26,880 --> 00:06:29,120
enterprise. 
It was really quite challenging 

101
00:06:29,440 --> 00:06:31,320
and they kept running out of 
money. 

102
00:06:31,560 --> 00:06:33,760
So they kept having to go back 
to the investors, getting new 

103
00:06:33,760 --> 00:06:35,440
investors, getting more people 
in. 

104
00:06:35,800 --> 00:06:39,840
They sold paper peak shows in 
order to generate income. 

105
00:06:40,040 --> 00:06:43,080
They'd bring visitors to look at
the tunnelling constructions, 

106
00:06:43,080 --> 00:06:44,880
try and raise some of that 
money. 

107
00:06:45,280 --> 00:06:48,360
And actually at a point they 
they just completely ran out of 

108
00:06:48,360 --> 00:06:50,800
money. 
I had to block up the tunnel. 

109
00:06:50,920 --> 00:06:54,640
They're to stop construction. 
Construction stopped for about 

110
00:06:54,640 --> 00:07:00,160
the 7-8 years at that point. 
Mark Brunel spent years 

111
00:07:00,160 --> 00:07:02,520
petitioning, campaigning, 
writing letters. 

112
00:07:02,880 --> 00:07:05,000
So anyone who would listen to 
say we need to finish this 

113
00:07:05,000 --> 00:07:07,200
tunnel, we need to absolutely 
finish this tunnel. 

114
00:07:07,440 --> 00:07:10,400
And then the Duke of Wellington 
eventually got involved and 

115
00:07:10,400 --> 00:07:13,280
actually it was support from the
government meant that they could

116
00:07:13,280 --> 00:07:17,160
finally finish the project. 
So yeah, it had a, even though 

117
00:07:17,160 --> 00:07:21,000
it was intended to be a sort of 
commercial project, it was 

118
00:07:21,000 --> 00:07:23,600
really quite financially 
challenging the whole time of 

119
00:07:23,600 --> 00:07:25,720
it, the whole 18 years of its 
construction. 

120
00:07:26,560 --> 00:07:30,440
So what inspired Mark Brunel to 
undertake such an ambitious 

121
00:07:30,440 --> 00:07:34,720
engineering project anyway? 
There was a real kind of 

122
00:07:34,720 --> 00:07:40,040
commercial reason for wanting to
dig, dig this tunnel to connect 

123
00:07:40,040 --> 00:07:42,600
up the docks on either side of 
the river. 

124
00:07:42,600 --> 00:07:46,560
That was really important, and 
it made a lot of sense at that 

125
00:07:46,560 --> 00:07:49,600
time. 
The thing that really made his 

126
00:07:49,600 --> 00:07:53,200
project a success where others 
had failed was the tunnelling 

127
00:07:53,200 --> 00:07:56,520
shield that he'd patented in 
1818. 

128
00:07:56,760 --> 00:08:01,560
And it was a way of protecting 
both the miners, the people 

129
00:08:01,560 --> 00:08:05,320
doing the tunneling, but also 
protecting the tunnel itself as 

130
00:08:05,320 --> 00:08:09,240
construction was happening. 
And the inspiration for that 

131
00:08:09,840 --> 00:08:13,920
came from something called a 
shipworm, the humble Teredo 

132
00:08:13,920 --> 00:08:17,760
Navales, which is not a worm at 
all, in fact it's a mollusk. 

133
00:08:18,120 --> 00:08:22,680
But Mark Brunel, before he came 
to London, was in Portsmouth. 

134
00:08:22,680 --> 00:08:26,040
He was part of the Royal Navy 
and he saw first hand the kind 

135
00:08:26,040 --> 00:08:30,760
of havoc that these sort of tiny
mollusks would wrought on all 

136
00:08:30,760 --> 00:08:34,039
the Royal Navy ships. 
So they would they'd dig hole 

137
00:08:34,320 --> 00:08:38,039
using, using the kind of shells 
at the top of their heads to dig

138
00:08:38,039 --> 00:08:39,880
these holes in the Timbers of 
ship. 

139
00:08:40,280 --> 00:08:43,799
But the really clever thing that
they do is they then create a 

140
00:08:43,799 --> 00:08:46,040
protective casing around 
themselves. 

141
00:08:46,280 --> 00:08:49,600
And that was the thing that 
previous attempts to dig a 

142
00:08:49,600 --> 00:08:53,320
tunnel under a river had failed 
because there wasn't this sort 

143
00:08:53,320 --> 00:08:58,280
of protective casing. 
So when Mark passages his 

144
00:08:58,720 --> 00:09:03,120
tunneling Shields, it had this 
kind of wooden cover for miners 

145
00:09:03,160 --> 00:09:05,800
to protect them for any kind of 
collapse from the soft earth. 

146
00:09:06,080 --> 00:09:09,720
But behind them you'd have these
brick layers come in and then 

147
00:09:09,720 --> 00:09:12,800
they would line the tunnel with 
bricks, which meant it could 

148
00:09:12,800 --> 00:09:17,080
withstand the pressure from sort
of the water and the geology 

149
00:09:17,080 --> 00:09:19,400
above. 
So that was being inspired by 

150
00:09:19,400 --> 00:09:22,680
nature is one of the great 
elements of the Thames Tunnel 

151
00:09:22,680 --> 00:09:25,960
story. 
So his focus wasn't on really 

152
00:09:25,960 --> 00:09:29,920
the the tunnelling as it were, 
because if we think of within 

153
00:09:29,920 --> 00:09:33,160
working in the Navy and 
reinventing that block making 

154
00:09:33,160 --> 00:09:38,000
system, his is actually the 
fixing a problem that no one 

155
00:09:38,000 --> 00:09:39,400
else could. 
They could do the bit of the 

156
00:09:39,400 --> 00:09:42,200
tunnelling, but it was the 
collapsing which they need some 

157
00:09:42,200 --> 00:09:46,680
help with. 
You have a model in the Museum 

158
00:09:46,840 --> 00:09:49,560
of this shield. 
Can you tell us a little bit 

159
00:09:49,560 --> 00:09:56,000
more about it please? 
It was made-up of 36 cells is 

160
00:09:56,000 --> 00:09:58,200
what they were called. 
They're all, all about the size 

161
00:09:58,200 --> 00:10:00,600
of a man. 
There were no women, as far as 

162
00:10:00,600 --> 00:10:03,240
we know, involved in the 
construction of the Thames 

163
00:10:03,240 --> 00:10:07,760
Tunnel, but you had sort of 12 
cells along, so 12 men along and

164
00:10:07,760 --> 00:10:10,520
three levels, so bottom, middle 
and top. 

165
00:10:11,080 --> 00:10:14,960
And each, each miner in front of
them had a series of polling 

166
00:10:14,960 --> 00:10:18,440
boards, so just wooden panels. 
And they'd remove each wooden 

167
00:10:18,440 --> 00:10:21,680
panel, dig behind it by hand. 
This is all being done by hand 

168
00:10:21,680 --> 00:10:23,240
tools. 
There's no machinery. 

169
00:10:23,600 --> 00:10:26,760
And all 36 of them would dig the
width of a brick. 

170
00:10:27,320 --> 00:10:30,040
And once they dug, they'd return
the polling board, do the same 

171
00:10:30,040 --> 00:10:33,200
with the next polling board. 
And by the time the whole thing 

172
00:10:33,200 --> 00:10:36,040
had gone, they dug out the width
of this brick. 

173
00:10:36,240 --> 00:10:39,120
The whole thing would move 
forward on a sort of series of 

174
00:10:39,120 --> 00:10:42,480
kind of cranks and screws and 
then the brick layers would come

175
00:10:42,480 --> 00:10:46,880
in and do their level. 
So it's really painstaking work 

176
00:10:47,400 --> 00:10:50,640
that they do. 
And yeah, if for the poor miners

177
00:10:50,640 --> 00:10:54,080
on the bottom, they're standing 
in Thames Water, which isn't 

178
00:10:54,080 --> 00:10:57,320
that lovely to stand in now, but
at this time it was, this is pre

179
00:10:57,320 --> 00:10:59,640
Basil Jet. 
This is, it's a, the Thames is 

180
00:10:59,640 --> 00:11:02,880
an open sewer. 
But they were provided with 

181
00:11:02,880 --> 00:11:05,280
boots by the Thames Tunnel 
Company. 

182
00:11:05,400 --> 00:11:07,240
So that would that would help 
them. 

183
00:11:07,280 --> 00:11:10,360
The only thing is they did have 
to share those boots with all of

184
00:11:10,360 --> 00:11:14,240
the other miners, so you come 
into work and have to get into 

185
00:11:14,240 --> 00:11:17,280
someone's stinky wet. 
Boots, I couldn't do that. 

186
00:11:17,520 --> 00:11:20,920
Oh yeah, it's it's 100 times 
worse than bowling shoes. 

187
00:11:20,920 --> 00:11:24,240
It's horrible. 
So these miners literally at the

188
00:11:24,240 --> 00:11:27,160
mud face, are these experienced 
miners? 

189
00:11:27,160 --> 00:11:29,920
Are they nabbies? 
What's their skill set? 

190
00:11:31,880 --> 00:11:35,680
So we think that they're sort of
the miners and the tunnelers at 

191
00:11:35,680 --> 00:11:37,200
the mud face. 
I really like that. 

192
00:11:37,200 --> 00:11:38,880
I'm stealing that. 
I'm going to use that. 

193
00:11:39,200 --> 00:11:43,480
They were experienced miners 
from places like Somerset and 

194
00:11:43,480 --> 00:11:47,640
they were employed for their 
skill in this work at the brick 

195
00:11:47,640 --> 00:11:49,680
layers. 
I think were the most skilled 

196
00:11:49,680 --> 00:11:52,720
employees. 
And then they were the ones that

197
00:11:52,720 --> 00:11:55,360
tried to go on strike because 
they weren't big paid enough. 

198
00:11:55,360 --> 00:11:59,160
But you also had but lots of 
these, lots of labourers moving 

199
00:11:59,160 --> 00:12:01,760
the spoil. 
So you had a bit of a sort of 

200
00:12:01,760 --> 00:12:05,000
hierarchy, lots of different 
jobs, more, some more skilled, 

201
00:12:05,000 --> 00:12:07,200
some less skilled. 
When you're talking about 

202
00:12:07,200 --> 00:12:11,560
skilled labour, did they have a 
little shanty town where all the

203
00:12:11,560 --> 00:12:15,560
workers live together? 
A lot of them lived quite lived 

204
00:12:15,600 --> 00:12:18,640
locally. 
So the way that the kind of 

205
00:12:18,640 --> 00:12:22,720
shift pattern works was the 
shield was always, it was always

206
00:12:22,720 --> 00:12:24,400
an operation, it was always 
going. 

207
00:12:24,400 --> 00:12:27,280
So you have sort of eight hours 
on, 8 hours off. 

208
00:12:27,680 --> 00:12:30,760
So you would finish your shift 
and then another miner would 

209
00:12:30,760 --> 00:12:34,880
come and replace you and then 
you'd swap that way. 

210
00:12:35,240 --> 00:12:38,400
One of the things about the 
Brunels that some of the workers

211
00:12:38,720 --> 00:12:42,360
certainly appeared to appreciate
is that they were very hands on 

212
00:12:42,360 --> 00:12:44,720
employers. 
Isn't Bard King de Brunel. 

213
00:12:44,720 --> 00:12:50,480
He was only 19 when the project 
started and he we've been 

214
00:12:50,480 --> 00:12:53,080
talking about, you see the 
original sort of nepo baby 

215
00:12:53,080 --> 00:12:56,240
because it was his dad got him 
the job and he then went on to 

216
00:12:56,240 --> 00:12:58,440
be this incredible civil 
engineers. 

217
00:12:58,600 --> 00:13:01,640
But he's really learned his 
craft under his dad on the 

218
00:13:01,640 --> 00:13:05,760
Thames Tunnel project. 
But he was, he was really, as 

219
00:13:05,760 --> 00:13:08,920
far as we know, quite liked and 
quite well respected by a lot of

220
00:13:08,920 --> 00:13:12,360
the workers, not necessarily all
of them because he was really 

221
00:13:12,440 --> 00:13:14,680
hands on. 
He was a bit of a workaholic 

222
00:13:14,680 --> 00:13:17,120
even then in the early days of 
his career. 

223
00:13:17,440 --> 00:13:20,240
He'd sleep in the tunnel 
sometime. 

224
00:13:20,240 --> 00:13:22,240
He just, he was like, I need to 
be back here in a couple of 

225
00:13:22,240 --> 00:13:24,240
hours to check, so I'll just 
stay here. 

226
00:13:24,600 --> 00:13:27,800
So yeah, it was a real, it was 
like a sort of mini town. 

227
00:13:27,960 --> 00:13:31,840
There were all these sorts of 
industries around the blacksmith

228
00:13:31,840 --> 00:13:35,360
forges, people making bricks, 
lots of things happening. 

229
00:13:35,960 --> 00:13:38,080
It was very industrial and 
bustly. 

230
00:13:38,080 --> 00:13:41,880
And if you come to the museum 
where the Thames Tunnel is, it's

231
00:13:41,880 --> 00:13:44,520
not like that today. 
It's like this sort of sleepy 

232
00:13:44,760 --> 00:13:47,720
hidden London village. 
It's very quiet. 

233
00:13:48,360 --> 00:13:50,440
But 200 years ago, it would not 
have been like that. 

234
00:13:50,440 --> 00:13:53,200
You've had, you've had people 
shouting, swearing. 

235
00:13:53,200 --> 00:13:55,480
Probably half of them were 
drunk. 

236
00:13:55,720 --> 00:13:57,840
They were given only. 
Yeah, the other half were 

237
00:13:57,840 --> 00:14:00,360
asleep, presumably. 
But they, they were given 

238
00:14:00,360 --> 00:14:03,400
whiskey as part of their sort 
of, presumably because the 

239
00:14:03,400 --> 00:14:06,640
conditions were so hard. 
And it was, this is how you get 

240
00:14:06,640 --> 00:14:10,760
people into work when it's such 
a kind of tough, challenging 

241
00:14:10,760 --> 00:14:11,440
job. 
Yeah. 

242
00:14:11,800 --> 00:14:14,280
It's really interesting what 
you're saying about how some of 

243
00:14:14,280 --> 00:14:19,200
the work has really appreciated 
IK being hands on because I was 

244
00:14:19,200 --> 00:14:23,840
reading his obituary in the 
Engineer magazine and it was 

245
00:14:23,840 --> 00:14:27,400
very picky saying he got too 
involved and too hands on. 

246
00:14:27,520 --> 00:14:31,440
But of course written by people 
who wouldn't even think of being

247
00:14:31,440 --> 00:14:33,680
hands on. 
So you've got to keep the 

248
00:14:33,680 --> 00:14:36,920
workers happy. 
If you think 8 hour shift that 

249
00:14:36,920 --> 00:14:40,680
is gruelling with the amount of 
stuff you're having to step 

250
00:14:40,680 --> 00:14:43,640
through and work in. 
What about the air quality as 

251
00:14:43,640 --> 00:14:47,120
well? 
Yeah, the air quality was not 

252
00:14:47,120 --> 00:14:49,080
great. 
So if you think about it, the 

253
00:14:49,080 --> 00:14:52,440
air's only coming from this sort
of from this kind of shaft on 

254
00:14:52,440 --> 00:14:55,120
the southern, on the Rotherhide 
side of the river. 

255
00:14:55,120 --> 00:14:57,120
That's where your kind of air is
coming in from. 

256
00:14:57,120 --> 00:15:02,880
And the further under the Thames
you go, the less good that air 

257
00:15:02,880 --> 00:15:06,280
quality becomes. 
Add to that the fact that you're

258
00:15:06,280 --> 00:15:10,360
stepping in Thames Water, which 
is basically human waste. 

259
00:15:10,760 --> 00:15:14,040
And then also the other 
challenge that they had is as 

260
00:15:14,040 --> 00:15:16,920
they were digging, they'd 
occasionally encounter sort of 

261
00:15:16,920 --> 00:15:19,400
pockets of methane or other 
gases. 

262
00:15:19,680 --> 00:15:23,880
And bearing in mind that this is
entirely lit by gas lamp, that 

263
00:15:23,880 --> 00:15:27,440
explosions were not uncommon. 
There were also times they'd 

264
00:15:27,440 --> 00:15:31,280
encounter, I think certainly I 
think it was sulfuric acid. 

265
00:15:31,280 --> 00:15:34,320
It was certainly an acid. 
And we've got reports of people 

266
00:15:34,320 --> 00:15:38,160
suffering from what was known as
tunnel blindness, usually 

267
00:15:38,160 --> 00:15:43,240
temporarily but sometimes not. 
So it's really not a this is 

268
00:15:43,240 --> 00:15:47,000
Victorian health and safety at 
its best in in that it's 

269
00:15:47,000 --> 00:15:51,560
completely non existent. 
And what were the Brunel's 

270
00:15:52,720 --> 00:15:56,200
feelings? 
Thoughts on the kind of human 

271
00:15:56,200 --> 00:16:00,720
cost? 
So that's, that's a really 

272
00:16:00,720 --> 00:16:03,560
interesting question. 
Both Mark and Isenbard were 

273
00:16:04,040 --> 00:16:07,080
worked very hard. 
They were very quite driven, 

274
00:16:07,080 --> 00:16:11,680
quite motivated people. 
And we have a there's an entry 

275
00:16:11,680 --> 00:16:15,960
in Mark Brunel's diary from sort
of Christmas one year quite 

276
00:16:15,960 --> 00:16:18,720
early on in the project where 
he's I can't believe that they 

277
00:16:18,720 --> 00:16:21,520
want Christmas off. 
I can't believe that they don't 

278
00:16:21,520 --> 00:16:23,280
want. 
So he comes across as a real 

279
00:16:23,280 --> 00:16:27,960
propest group, like a real sort 
of similarly was it's quite well

280
00:16:27,960 --> 00:16:30,560
documented. 
He was, he works incredibly hard

281
00:16:31,440 --> 00:16:34,920
ideas, modern ideas like 
self-care, very much not, not 

282
00:16:34,920 --> 00:16:36,520
something that he would 
recognize. 

283
00:16:36,920 --> 00:16:41,840
But actually when the workers 
went on strike, this was a week 

284
00:16:41,840 --> 00:16:45,400
into Isabad being resident 
engineer. 

285
00:16:45,760 --> 00:16:49,040
So he's just been given his 
first pickle job by your dad. 

286
00:16:49,360 --> 00:16:52,360
And then he's told, oh, now 
you've got to go and break this 

287
00:16:52,360 --> 00:16:56,040
strike, which he does because 
that's his job and that's what 

288
00:16:56,040 --> 00:16:58,920
he's been told to do. 
But in his sort of personal 

289
00:16:58,920 --> 00:17:02,560
diary he write, I don't really 
understand why these people 

290
00:17:02,800 --> 00:17:05,000
shouldn't be getting properly 
paid. 

291
00:17:05,000 --> 00:17:07,160
They should be compensated for 
their work. 

292
00:17:07,440 --> 00:17:11,000
So it's quite interesting that 
kind of public, private persona 

293
00:17:11,000 --> 00:17:13,040
as well. 
So yeah, they're quite, they 

294
00:17:13,079 --> 00:17:16,520
were very involved certainly 
both Brunel's in the kind of 

295
00:17:16,520 --> 00:17:18,359
day-to-day. 
But yeah, their attitude 

296
00:17:18,359 --> 00:17:21,599
probably differed in the way 
that they responded to the 

297
00:17:21,599 --> 00:17:24,359
people around them and. 
What about the public perception

298
00:17:24,359 --> 00:17:28,079
then with this tunnel evolving 
and they must have been seeing 

299
00:17:28,319 --> 00:17:33,480
adverts to invest et cetera? 
So I think like anything new and

300
00:17:33,480 --> 00:17:37,640
different and a bit novel and 
that there's an equal mix of 

301
00:17:37,640 --> 00:17:40,040
kind of fascination and 
frightening. 

302
00:17:40,480 --> 00:17:43,400
And I think people really saw 
that they, we've got reports of 

303
00:17:43,400 --> 00:17:48,240
the local vicar in his weekly 
sermon after one of the floods 

304
00:17:48,280 --> 00:17:51,320
saying that's what you get, but 
for digging towards the devil. 

305
00:17:51,680 --> 00:17:54,600
And that there was this real 
sense that hell was down there, 

306
00:17:54,640 --> 00:17:58,720
why are you going down there? 
And so some people really were 

307
00:17:58,720 --> 00:18:02,280
quite frightened by it. 
I thought it was really a bit 

308
00:18:02,280 --> 00:18:04,640
beyond the pale. 
And other people were just 

309
00:18:04,640 --> 00:18:08,400
completely fascinated. 
So that we've got some, we've 

310
00:18:08,400 --> 00:18:12,600
got some amazing accounts of 
people coming to visit the 

311
00:18:12,600 --> 00:18:15,320
Thames Tunnel because it was one
of the ways that they generated 

312
00:18:15,320 --> 00:18:18,320
income for the project. 
Mark Brunel didn't like it. 

313
00:18:18,680 --> 00:18:21,080
He was worried. 
Interestingly, he was worried 

314
00:18:21,080 --> 00:18:22,520
about the safety of the 
visitors. 

315
00:18:22,520 --> 00:18:24,400
He thought this is quite a risky
project. 

316
00:18:24,400 --> 00:18:27,760
I don't think we should be just 
letting you know, civilian down 

317
00:18:27,760 --> 00:18:30,960
here. 
But the the actress Fanny 

318
00:18:30,960 --> 00:18:36,000
Campbell came to visit and she 
was absolutely fascinated by by 

319
00:18:36,000 --> 00:18:37,720
the engineering that was taking 
place. 

320
00:18:37,960 --> 00:18:41,280
And another person that your 
listers might have heard of is 

321
00:18:41,280 --> 00:18:43,960
Anne Lister. 
Gentleman Jack from the TV 

322
00:18:43,960 --> 00:18:48,120
series tried to bring a date to 
the Thames Tunnel and the date 

323
00:18:48,280 --> 00:18:50,320
wasn't keen. 
I think the date never turned up

324
00:18:50,320 --> 00:18:54,080
but analyst that went on her own
and has written about the the 

325
00:18:54,080 --> 00:18:55,720
fascinating engineering that was
happening. 

326
00:18:55,720 --> 00:18:58,960
So there were lots of people who
were really quite swept up in in

327
00:18:58,960 --> 00:19:02,600
this exciting project. 
And are there any particular 

328
00:19:02,600 --> 00:19:06,400
artifacts or maybe stories in 
the museum that you feel really 

329
00:19:06,400 --> 00:19:10,720
capture that spirit or drama of 
the Thames Tunnel project? 

330
00:19:12,440 --> 00:19:15,680
So I think we've got some 
fantastic, we've got some 

331
00:19:15,680 --> 00:19:17,520
fantastic kind of works on 
paper. 

332
00:19:17,880 --> 00:19:22,120
And one of the things that isn't
on display yet, but will be is a

333
00:19:22,600 --> 00:19:24,840
this sort of beautiful cardboard
model. 

334
00:19:25,040 --> 00:19:30,200
It's handmade and it shows the 
tunnel in progress. 

335
00:19:30,200 --> 00:19:33,560
It shows the tunneling shield, 
complete with little, absolutely

336
00:19:33,600 --> 00:19:35,320
tiny. 
It's about centimeter and a half

337
00:19:35,680 --> 00:19:38,520
miners and brick layers. 
And they're paper. 

338
00:19:38,520 --> 00:19:40,920
They're absolutely, they're so 
delicate. 

339
00:19:41,840 --> 00:19:44,840
And the one we have in our 
collection was Mark Brunell's. 

340
00:19:45,200 --> 00:19:49,080
But these were made and sold. 
There was a little guide book 

341
00:19:49,080 --> 00:19:52,440
that went with them that is on 
display in the museum and they 

342
00:19:52,440 --> 00:19:54,920
were sold to raise money for the
project. 

343
00:19:54,920 --> 00:19:57,640
They were, oh, look, we've made 
this lovely shiny the way that 

344
00:19:57,640 --> 00:20:00,680
you might get a brochure now if 
you're thinking about investing 

345
00:20:00,680 --> 00:20:04,560
in something instead, in the 
1820s, you'd get this sort of 

346
00:20:04,560 --> 00:20:08,480
beautiful little paper model. 
And I just think that sort of 

347
00:20:08,480 --> 00:20:11,760
captures. 
But it's also this sort of 

348
00:20:11,760 --> 00:20:16,640
stylized view of what it was 
like that doesn't really capture

349
00:20:16,960 --> 00:20:20,360
the sort of grim reality. 
And I suppose that's one thing 

350
00:20:20,560 --> 00:20:23,520
that all of the sort of images 
you get because of who produced 

351
00:20:23,520 --> 00:20:26,320
them show this kind of 
relatively sanitized view. 

352
00:20:26,320 --> 00:20:28,840
But we do have some amazing 
sketches as well that sort of 

353
00:20:28,840 --> 00:20:33,360
show the tunnel after the floods
that sort of give you a sense of

354
00:20:33,360 --> 00:20:35,640
some of the sort of danger that 
they were dealing with. 

355
00:20:35,720 --> 00:20:38,520
And how did the opening of this 
tunnel, if you've got this 

356
00:20:38,520 --> 00:20:43,240
little shanty town, how did that
turn and also wider area of 

357
00:20:43,240 --> 00:20:47,160
London affect once the this 
tunnel was finally open? 

358
00:20:48,880 --> 00:20:52,400
So I think the important thing 
with the sort of tunnel finally 

359
00:20:52,400 --> 00:20:56,120
being open after after 18 years 
of construction and digging, 

360
00:20:56,760 --> 00:20:59,600
unfortunately, even though it 
was always intended to be this 

361
00:20:59,600 --> 00:21:03,320
kind of cargo tunnel to take 
horses and carts with cargo from

362
00:21:03,320 --> 00:21:04,720
one side of the river to the 
other. 

363
00:21:05,160 --> 00:21:08,920
In order to facilitate that, 
they needed to build what they 

364
00:21:08,920 --> 00:21:12,400
referred to as the grand descent
safts like we've got on the 

365
00:21:12,400 --> 00:21:16,320
North and South side at the 
moment, but much bigger, which 

366
00:21:16,320 --> 00:21:19,080
would have given you a much sort
of a greater diameter for horse 

367
00:21:19,080 --> 00:21:22,520
and carts to go down. 
By the time they'd finished the 

368
00:21:22,520 --> 00:21:27,200
project 18 years later, there 
was neither the sort of finance 

369
00:21:27,200 --> 00:21:29,280
available. 
That's the the lenders. 

370
00:21:29,280 --> 00:21:31,680
The investors were just like, 
no, we're not giving you any 

371
00:21:31,680 --> 00:21:35,240
more money towards this project.
It's already taken enough of my 

372
00:21:35,240 --> 00:21:39,920
money and they there wasn't 
enough money to purchase the 

373
00:21:39,920 --> 00:21:43,880
land to do those grander cents. 
But even if they had the money, 

374
00:21:44,120 --> 00:21:48,240
the land had actually been sold.
Don't ask me why they didn't at 

375
00:21:48,280 --> 00:21:50,800
the beginning of the project, 
go, we need that land, let's buy

376
00:21:50,800 --> 00:21:53,120
it now. 
That was characteristic of the 

377
00:21:53,280 --> 00:21:56,120
business decisions that they 
were making at that time. 

378
00:21:56,800 --> 00:22:00,160
So because they didn't build 
those descents, which meant that

379
00:22:00,160 --> 00:22:03,560
they could move cargo. 
When it opened in 1843, the 

380
00:22:03,720 --> 00:22:06,600
Thames Tunnel opened as a 
pedestrian foot tunnel. 

381
00:22:06,960 --> 00:22:09,160
So not the cargo tunnel it was 
meant to be. 

382
00:22:09,360 --> 00:22:12,920
You paid a penny to go through 
it, which is much less than the 

383
00:22:12,920 --> 00:22:15,600
sort of cargo tolls that they've
been anticipating. 

384
00:22:16,040 --> 00:22:19,240
So they needed to generate 
revenue some other way. 

385
00:22:19,520 --> 00:22:22,240
So it opened huge fanfare in 
1843. 

386
00:22:22,240 --> 00:22:24,840
It was really exciting. 
People had been waiting for this

387
00:22:24,840 --> 00:22:30,040
thing hugely popular, but 
actually they needed, they 

388
00:22:30,040 --> 00:22:31,720
needed other ways of generating 
income. 

389
00:22:31,720 --> 00:22:35,800
So it became this underwater 
shopping arcade that sort of you

390
00:22:35,800 --> 00:22:37,840
had people buying and selling 
wares. 

391
00:22:38,160 --> 00:22:41,960
It became this just huge tourist
attraction was really popular. 

392
00:22:44,080 --> 00:22:47,280
And what about special events 
then? 

393
00:22:47,480 --> 00:22:49,600
What was happening to get people
down there? 

394
00:22:51,040 --> 00:22:54,200
The one of the other things that
they did in order to make money 

395
00:22:54,200 --> 00:22:57,880
and recoup these costs where 
they ran things for fancy fares.

396
00:22:58,080 --> 00:23:01,360
So they would have these sort of
big extravaganza type events 

397
00:23:01,440 --> 00:23:05,560
with all sorts of Victorian 
entertainment, including I think

398
00:23:05,560 --> 00:23:07,840
my there's two that are 
favourites for me. 

399
00:23:07,840 --> 00:23:11,480
One is electricity. 
That was, see that was such a 

400
00:23:11,480 --> 00:23:14,920
novelty at this point that was 
put on one of the posters as 

401
00:23:14,920 --> 00:23:18,400
something to come and see. 
And a woman, someone called the 

402
00:23:18,400 --> 00:23:23,280
Mysterious Lady and she was a 
sort of mind reader type act. 

403
00:23:23,600 --> 00:23:26,920
So she was a sort of proto 
Derren Brown in the Victorian 

404
00:23:26,920 --> 00:23:29,640
era. 
So all sorts of interesting, 

405
00:23:29,680 --> 00:23:33,000
interesting sort of Victorian 
entertainment you come and see 

406
00:23:33,160 --> 00:23:37,520
in the tunnel. 
And what kind of inspiration did

407
00:23:37,520 --> 00:23:39,320
people take from this tunnel 
then? 

408
00:23:39,360 --> 00:23:42,000
Did it have a knock on effect 
elsewhere in other engineering 

409
00:23:42,000 --> 00:23:46,840
projects? 
In terms of tunnelling, one of 

410
00:23:46,840 --> 00:23:49,400
the things that we get asked at 
the museum is are you the 

411
00:23:49,400 --> 00:23:51,760
Rotherhithe Tunnel? 
And we have to explain that the 

412
00:23:51,760 --> 00:23:55,080
Thames Tunnel is now part of the
Windrush line. 

413
00:23:55,080 --> 00:23:57,880
It's actually part of the 
Overground network and the 

414
00:23:57,880 --> 00:24:01,360
Rotherhithe Tunnel came later 
and is the road tunnel. 

415
00:24:01,760 --> 00:24:04,120
But what I think is really 
interesting about the different 

416
00:24:04,120 --> 00:24:10,120
tunnel under the Thames, 
particularly in London, is they 

417
00:24:12,040 --> 00:24:16,960
they took another generation for
people to be ready to try to dig

418
00:24:16,960 --> 00:24:20,240
another tunnel onto the Thames. 
So there's quite a good chunk of

419
00:24:20,240 --> 00:24:24,360
time between the Thames Tunnel 
being started and finished and 

420
00:24:24,360 --> 00:24:26,480
then people looking at the 
rather high tunnel, the 

421
00:24:26,480 --> 00:24:29,480
Greenwich Foot tunnel, the 
Blackwall Tunnel, they were all 

422
00:24:29,480 --> 00:24:32,040
completed within about 15 years 
of each other. 

423
00:24:32,240 --> 00:24:36,480
But it took a good sort of 50 
years between the Thames Tunnel 

424
00:24:36,480 --> 00:24:39,760
being completed to someone 
going, OK, I think we, I think 

425
00:24:39,760 --> 00:24:42,400
we're ready for this again, 
because it was my take on it is 

426
00:24:42,400 --> 00:24:45,960
that it was such a sort of 
undertaking and a bit of an 

427
00:24:45,960 --> 00:24:50,920
ordeal that it took a long time 
for the next generation of 

428
00:24:50,920 --> 00:24:55,480
tunnels to be dug. 
Today all tunneling projects 

429
00:24:55,960 --> 00:25:01,000
have this that their foundation 
was laid by Mark Brunel 200 

430
00:25:01,000 --> 00:25:03,000
years ago. 
So the tunnel boring machines 

431
00:25:03,000 --> 00:25:07,080
that made Crossrail possible, 
that are making HS2 possible, 

432
00:25:07,080 --> 00:25:10,840
that made the Channel Tunnel 
possible, that's all a sort of 

433
00:25:10,840 --> 00:25:14,960
modern version of Mark Brunel's 
tunneling shield. 

434
00:25:16,320 --> 00:25:17,960
That's a really nice way to to 
put it. 

435
00:25:18,280 --> 00:25:22,480
I remember reading a bit of a 
stat on a press release that we 

436
00:25:22,480 --> 00:25:27,760
in Britain are leading the 
tunnelling engineering world and

437
00:25:27,760 --> 00:25:31,520
we have the only apprenticeships
who tunnelling on offer. 

438
00:25:33,120 --> 00:25:34,480
Go us. 
There you go. 

439
00:25:34,680 --> 00:25:36,440
It's good. 
It's very important. 

440
00:25:36,480 --> 00:25:39,960
We would, if you, I hope that 
your listeners are after this 

441
00:25:39,960 --> 00:25:43,800
thinking, start to notice 
actually when they go under the 

442
00:25:43,800 --> 00:25:46,160
river a little bit more and 
actually there's sort of 

443
00:25:46,160 --> 00:25:49,120
engineering that goes into that.
Actually, that's a really good 

444
00:25:49,120 --> 00:25:51,280
point. 
So you're talking about a 

445
00:25:51,280 --> 00:25:56,000
Victorian tunnel, which how many
trains on the Overground go 

446
00:25:56,000 --> 00:25:59,240
through it a day? 
What about any restoration or 

447
00:25:59,240 --> 00:26:02,440
anything that's been going on? 
Or are we really on borrowed 

448
00:26:02,440 --> 00:26:07,040
time? 
Yeah, I think it is the sort of 

449
00:26:07,040 --> 00:26:10,440
last part of the story. 
So I always think of the sort of

450
00:26:10,440 --> 00:26:13,400
10% of stories being so 3 chunks
really. 

451
00:26:13,400 --> 00:26:16,960
They're the construction. 1820s 
to 1843. 

452
00:26:17,200 --> 00:26:20,760
There's it sort of shopping 
arcade and fantasy fairs kind of

453
00:26:20,760 --> 00:26:23,480
time sort of 1843 to the late 
1860s. 

454
00:26:23,520 --> 00:26:28,560
And then in the 1860s it was 
sold to the London Metropolitan 

455
00:26:28,560 --> 00:26:31,080
Railway. 
It's got a second light as a 

456
00:26:31,080 --> 00:26:33,360
train tunnel. 
This is this is in the very 

457
00:26:33,360 --> 00:26:36,440
early days of the London 
Underground and steam trains. 

458
00:26:36,800 --> 00:26:39,600
And so it was sold to the 
Metropolitan Railway. 

459
00:26:39,600 --> 00:26:42,960
It became the East London Line, 
which kind of ran from 

460
00:26:42,960 --> 00:26:46,400
Whitechapel to New Cross. 
So it's not a very long line. 

461
00:26:46,640 --> 00:26:54,480
And then in 2011 when the East 
London Line became part of the 

462
00:26:54,480 --> 00:26:58,160
Overground, it all connected up 
and there's and it's now always 

463
00:26:58,160 --> 00:27:01,600
the kind of Windrush on me. 
And I think something like 

464
00:27:01,600 --> 00:27:05,840
60,000 people go through it 
every single day, which is just 

465
00:27:05,840 --> 00:27:12,640
a phenomenal amount in terms of 
restoration in the 1990s. 

466
00:27:12,800 --> 00:27:16,800
It was only in the 1990s, sorry,
I state that it the tunnel 

467
00:27:16,800 --> 00:27:20,920
itself was recognized as a sort 
of historically important 

468
00:27:21,280 --> 00:27:24,440
feature that it's been, it had 
trains running through it for 

469
00:27:24,440 --> 00:27:27,840
over 100 years by that point. 
But no one has really given it 

470
00:27:27,840 --> 00:27:30,120
much thought. 
And there were plans to put 

471
00:27:30,120 --> 00:27:36,600
shotcrete kind of concrete type 
material over the tunnel, over 

472
00:27:36,600 --> 00:27:40,840
Mark Brunel's fantastic tunnel. 
And it was only at, I think the 

473
00:27:40,840 --> 00:27:43,920
engineers were due on site at 
sort of 8:00 AM on the Monday 

474
00:27:43,920 --> 00:27:46,640
morning. 
And last thing on the Friday, 

475
00:27:46,640 --> 00:27:49,840
the minister for Heritage signed
a letter saying please don't put

476
00:27:49,840 --> 00:27:52,240
any shotcrete on Mark Brunel's 
tunnel. 

477
00:27:52,240 --> 00:27:56,960
So I think it is shotcreted 
under the Thames in the section 

478
00:27:56,960 --> 00:28:00,800
actually under the water. 
But the sections of the original

479
00:28:00,800 --> 00:28:03,600
tunnel on the sort of whopping 
and rather hide side are 

480
00:28:03,600 --> 00:28:07,320
protective and you can if you 
stand up whopping. 

481
00:28:07,320 --> 00:28:10,360
If you stand on the platform 
whopping and look back towards 

482
00:28:10,360 --> 00:28:16,040
rather Hive, you can just about 
see the double arch of Marc 

483
00:28:16,040 --> 00:28:19,520
Brunel's original tunnel. 
I tell you what gave me 

484
00:28:19,520 --> 00:28:23,600
goosebumps for 60,000 people a 
day going through the tunnel and

485
00:28:23,600 --> 00:28:25,560
one of them could be listening 
to this podcast. 

486
00:28:27,320 --> 00:28:29,640
They might be on it now 
listening to it now. 

487
00:28:29,640 --> 00:28:32,840
That would be amazing. 
If you are, just pop out on 

488
00:28:32,880 --> 00:28:34,720
Brother Hype and come and say hi
to her. 

489
00:28:34,840 --> 00:28:37,560
Well, there you go. 
What aspect of the tunnel's 

490
00:28:37,560 --> 00:28:44,320
history fascinates you most? 
I just love that it's this story

491
00:28:44,320 --> 00:28:51,240
of adaptability and kind of 
perseverance and continuing 

492
00:28:51,240 --> 00:28:54,560
against all odds because it was 
such a talented project. 

493
00:28:54,960 --> 00:28:59,600
And then it took so much longer 
than they thought it would and 

494
00:28:59,640 --> 00:29:02,200
but they completed it and they 
managed to make something really

495
00:29:02,200 --> 00:29:04,480
amazing. 
And unfortunately, both, both 

496
00:29:04,480 --> 00:29:08,760
Mark and isn't bad died before 
before the tunnel was sold to 

497
00:29:08,760 --> 00:29:10,360
the railways. 
They never saw it. 

498
00:29:10,360 --> 00:29:14,200
Kind of Second Life, there's a 
railway tunnel and I wonder how 

499
00:29:14,200 --> 00:29:17,720
they would think 200 years later
after they started construction 

500
00:29:18,040 --> 00:29:22,320
that, oh, it's being used by 
60,000 people every single day. 

501
00:29:22,320 --> 00:29:26,920
This tunnel has survived and as 
it's adapted and it's become 

502
00:29:26,920 --> 00:29:29,960
something else that's really 
genuinely useful. 

503
00:29:30,600 --> 00:29:33,160
And that's what I sort of love 
when people come into the museum

504
00:29:33,160 --> 00:29:35,520
and they we ask them how they 
got there and they're like, oh, 

505
00:29:35,520 --> 00:29:38,120
I just got on the Windrush line 
and from, from white Tupperware,

506
00:29:38,120 --> 00:29:39,800
I'm like, you've been through 
the tunnel. 

507
00:29:40,080 --> 00:29:43,560
You've already been through this
fantastic tunnel and now find 

508
00:29:43,560 --> 00:29:46,760
out about how it got there. 
So that's for me, I think is the

509
00:29:46,760 --> 00:29:50,040
story that I think is just so 
interesting about it. 

510
00:29:50,920 --> 00:29:55,240
And what about a particular 
object or that really tells the 

511
00:29:55,240 --> 00:29:58,560
most powerful story? 
What is the to see other than 

512
00:29:58,560 --> 00:30:02,080
the the shield model which I 
think is absolutely fantastic? 

513
00:30:02,120 --> 00:30:04,360
Yeah, I love all the stuff to do
with the construction. 

514
00:30:04,360 --> 00:30:09,280
I love all the sort of drawings 
and the models, but I think what

515
00:30:09,280 --> 00:30:13,320
I also think is just so 
fantastic are these paper peep 

516
00:30:13,320 --> 00:30:15,720
shows. 
And we've got one in our, one in

517
00:30:15,720 --> 00:30:19,000
our collection that and these 
are things that were sold to 

518
00:30:19,000 --> 00:30:23,360
raise money for the construction
itself and gave this idea of 

519
00:30:23,400 --> 00:30:26,200
what it was meant to look like. 
And we've got this absolutely 

520
00:30:26,200 --> 00:30:28,200
brilliant one, which is quite 
rare because it's a double 

521
00:30:28,200 --> 00:30:32,360
layered Peep Show and the top 
layer shows you the river. 

522
00:30:32,600 --> 00:30:35,240
So it's showing you people on 
boats and some sort of ships, 

523
00:30:35,800 --> 00:30:39,080
but then underneath you can see 
the tunnel itself. 

524
00:30:39,080 --> 00:30:41,320
You can see the people walking 
through, having their 

525
00:30:41,320 --> 00:30:44,960
conversations. 
And I just, I love that it gives

526
00:30:44,960 --> 00:30:49,200
you the full context of where 
the tunnel is, that it is under 

527
00:30:49,200 --> 00:30:51,800
the river. 
And sometimes you forget that, 

528
00:30:52,280 --> 00:30:55,720
But just, yeah, the amount of 
kind of energy and effort and 

529
00:30:55,720 --> 00:30:59,200
engineering that has to go into 
taking something for granted. 

530
00:30:59,360 --> 00:31:01,000
I think it's quite lovely 
actually. 

531
00:31:02,440 --> 00:31:07,320
Your team are very busy at the 
moment with the creation of a 

532
00:31:07,360 --> 00:31:10,800
brand new exhibit opening on the
12th of September. 

533
00:31:10,800 --> 00:31:12,440
Can you tell us a little bit 
more about that? 

534
00:31:14,000 --> 00:31:16,560
Yeah, absolutely. 
But we're really excited about 

535
00:31:16,560 --> 00:31:22,840
this because we wanted to ask 
the question about how does Mark

536
00:31:22,840 --> 00:31:25,960
Grinnell, born and raised in 
front, has to leave, which is 

537
00:31:25,960 --> 00:31:30,080
the French Revolution end up 
digging a tunnel in rather highs

538
00:31:30,520 --> 00:31:33,080
in southeast London? 
How do you get from Rouen in 

539
00:31:33,080 --> 00:31:36,960
Normandy to southeast London? 
And I think that I think that's 

540
00:31:36,960 --> 00:31:39,280
such an interesting kind of 
premise. 

541
00:31:39,720 --> 00:31:43,960
And it means that we get to put 
on display some of our most kind

542
00:31:43,960 --> 00:31:48,520
of beautiful objects. 
And one of those objects which 

543
00:31:48,640 --> 00:31:52,760
absolutely love is a pair of 
shoe buckles and a silver with 

544
00:31:52,760 --> 00:31:55,400
jewels on. 
And they belonged to Mark 

545
00:31:55,560 --> 00:31:59,000
Brunel. 
And I think they just give such 

546
00:31:59,000 --> 00:32:02,520
an indication of his kind of 
personality and his character 

547
00:32:02,800 --> 00:32:05,960
that this man who built this 
tunnel and this this really 

548
00:32:05,960 --> 00:32:09,280
gritty engineering project loved
a shiny shoe buckle. 

549
00:32:09,840 --> 00:32:13,400
And it also really speaks to his
political affiliations because 

550
00:32:13,400 --> 00:32:15,440
he was a royalist. 
It's one of the reasons why he 

551
00:32:15,440 --> 00:32:17,920
had to leave France during the 
revolution. 

552
00:32:18,280 --> 00:32:21,920
And the shoe buckles were a sort
of sign of his political 

553
00:32:21,920 --> 00:32:25,280
affiliation. 
And I and the fact that we have 

554
00:32:25,280 --> 00:32:27,840
those and these tiny little 
objects can tell such a big 

555
00:32:27,840 --> 00:32:29,520
story. 
I think it's just brilliant. 

556
00:32:29,520 --> 00:32:32,120
I'm really excited to share 
those with with our visitors. 

557
00:32:32,400 --> 00:32:34,720
Oh fantastic. 
You have very kindly shared us 

558
00:32:34,720 --> 00:32:38,680
some photos which we will be 
putting on the show notes in the

559
00:32:38,680 --> 00:32:42,400
video and of course on the 
transcript page of the website 

560
00:32:42,400 --> 00:32:44,320
anyway. 
But of course, you can go and 

561
00:32:44,320 --> 00:32:48,120
see these super shiny buckles 
with some really wonderful some 

562
00:32:48,120 --> 00:32:52,120
of the oldest artifacts in the 
museum's collection in this 

563
00:32:52,120 --> 00:32:56,160
exhibition, which is 12th of 
September to 15th of December 

564
00:32:56,160 --> 00:32:59,160
2025. 
We've also got some films that 

565
00:32:59,160 --> 00:33:04,680
we can enjoy. 
Yes, we're also doing a series 

566
00:33:04,680 --> 00:33:07,960
of film screenings all about the
French Revolution. 

567
00:33:07,960 --> 00:33:13,440
So we've got Dangerous Liaisons,
we've bought, we've got Marie 

568
00:33:13,440 --> 00:33:17,320
Antoinette and Napoleon. 
So that's four weeks, Timber 

569
00:33:17,320 --> 00:33:20,640
October every Wednesday. 
And the brilliant thing about 

570
00:33:20,640 --> 00:33:22,960
that is we are screening them in
our tunnel shop. 

571
00:33:23,400 --> 00:33:27,320
So the big structure that was 
sunk into the ground that made 

572
00:33:27,320 --> 00:33:30,600
the whole thing possible is now 
our major event space. 

573
00:33:30,600 --> 00:33:33,000
And you can come there and you 
can watch Marie Antoinette or 

574
00:33:33,000 --> 00:33:38,040
Napoleon and understand just 
that amazing story of how did 

575
00:33:38,040 --> 00:33:42,280
all these these events happening
in a different country end up 

576
00:33:42,520 --> 00:33:46,000
with kind of the world's first 
underwater tunnel in southeast 

577
00:33:46,000 --> 00:33:48,080
London. 
And hopefully you're going to 

578
00:33:48,080 --> 00:33:50,440
tell that the love story between
Mark and Sophia. 

579
00:33:51,840 --> 00:33:54,760
Oh, absolutely, yes. 
So actually we will be doing 

580
00:33:54,760 --> 00:33:58,880
some Valentine's Day events in 
2026, all about the love story 

581
00:33:58,880 --> 00:34:01,160
between Mark and Sophia. 
I think that's a whole other 

582
00:34:01,160 --> 00:34:03,320
podcast their love. 
Story, I'm up for that. 

583
00:34:05,400 --> 00:34:08,120
All right, Catherine, thank you 
so much for joining us today. 

584
00:34:08,120 --> 00:34:11,480
It just shows you, doesn't it, 
how important the tennis tunnel 

585
00:34:11,480 --> 00:34:14,400
is and we don't really think 
about it, we just use it. 

586
00:34:16,480 --> 00:34:20,639
Exactly. 
And if any of you lovely 

587
00:34:20,639 --> 00:34:25,560
listeners would like to visit 
the Brunel Museum, then we have
