Tower Bridge

Tower Bridge was a London bridge, over which people could cross the River Thames. The road which crossed the bridge was called Tower Bridge Road. While its northern landfall was located just beyond the eastern wall of the Tower of London, (TV: The Lie of the Land) its southern landfall was located in the London Borough of Southwark.

The Fifth Doctor's TARDIS materialised near the bridge in 1984. (TV: Resurrection of the Daleks)

Behind the scenes
VFX shots of the CyberKing in London, in 2009's The Next Doctor, had to be fixed by The Mill after producer Susie Liggat noticed that 1851 London contained the Tower Bridge, which wouldn't be built for another four or so decades.
