The Thames Tunnel is the world’s oldest underwater tunnel, first opened to the public in 1843. Originally for pedestrians, it was later converted into a railway line. It’s still in use today as a train tunnel – part of the London Overground line that stretches from Rotherhithe to Wapping Station.

While you can’t walk through the Thames Tunnel, you can head underground into the spectacular Grade II* listed Tunnel Shaft which once served as the Grand Entrance Hall for Victorian visitors. You can still see where the original staircases once would have been and hear the rumbling train carriages below. In the Engine House, you can explore the main museum exhibition which tells the story behind the Thames Tunnel and those who built it. View the museum displays, discover the collection of original Thames Tunnel memorabilia and Victorian peepshows, and look out for the large-scale models of the tunnelling shield and machinery.
