Tower of London

The tower set used to be immediately adjacent to Denver Street. It was removed around 1988 for the construction of the Earthquake show building which has replaced it.
The set was built for Tower of London (1939) starring Boris Karloff, Basil Rathbone and Vincent Price. That film marked Vincent Price’s horror film debut.
The castle also appeared as a concentration camp in Judgement at Nuremburg, starring Spencer Tracy, a Scottish castle in McMillan and Wife, an amusement park in Murder She Wrote, starring Angela Lansbury, and even a village on a distant planet in Buck Rogers in the 25th Century. It also appeared in Airwolf, when the helicopter of the title made a flying visit.
