The first tunnel in the world under a navigable river. Built between 1825 and 1843 using the tunnelling shield technology invented by Marc Brunel. It was originally intended to be used for horse-drawn traffic, but this never materialised. It was briefly profitable since it attracted tourist pedestrians so shops and entertainment were provided in the tunnel. It is now the link between Rotherhithe and Wapping stations on the London Overgound rail network. Not to be confused with the Rotherhithe Tunnel - used for road traffic.
