We're at Wapping, on the north side of Brunel's famous Thames tunnel
what do you mean you don't know about Brunel's famous Thames Tunnel ... ? This one!
The Thames Tunnel - designed as a foot tunnel, was built by Marc Brunel and his son Isimbard
and it opened in 1843.
It was the first known tunnel to be constructed underneath a navigable river
It was taken over by the railways in 1865, and became part of the East London Line,
and is of course now used by the Overground network.
If you've just passed through thought and never got out, you may not have seen the
commemorative plaques at each end, and at Wapping station too, where on the platforms there is artwork
depicting the construction of the tunnel.
But the best bit, is on the south side.
