Tower Bridge
Tube station: Tower Hill (Tube Map)

This incredible monument to Victorian engineering was completed in 1864 and is now one of the enduring symbols of London.

The twin towers and linking catwalk support a mechanism that raises the road so that big ships can pass through on their passage along the Thames.

The bridge, which, in its heyday, opened up to five times a day, is 150ft (40m) high when raised and 200ft (60m) wide. A steam engine used to do all the donkey work, but electricity took over in the 1970s.

There are fine views from here to the Tower of London and upstream towards HMS Belfast. Canary Wharf is easily visible downstream.
