The Thames Tunnel from Rotherhithe
The first tunnel ever to be built under a river. Engineered by Marc Brunel and his son Isambard. Opened as a pedestrian tunnel in 1843 and converted to a railway in 1865. Functioned as part of the London Underground until December 2007. Then it temporarily closed so the line could be converted to become part of the expanded 'Overground' network. It will shortly re-open - but on Fri & Sat 12/13 March 2010 it was opened to pedestrians for the first time in 145 years.
