[edit] History

Henry VIII once sent the Doctor to the Tower of London, which is where the Doctor wanted to be as that's where his TARDIS had also been taken. (DW: The Sensorites)

The Doctor was later imprisoned in the Tower of London again, where he shared a cell with Sir Walter Raleigh. (DW: The Mind of Evil)

The Doctor assisted Lady Jane Grey and was present at her execution at the Tower (The Nine-Day Queen).

The Doctor would end up there yet again, this time with Nyssa, after running afoul of Sir Isaac Newton. (BFA: Circular Time)

In 2006, UNIT headquarters was located beneath the Tower of London. (DW: The Christmas Invasion) The headquarters was still used in 2009, though UNIT also maintained mobile bases in lorry trucks. (DW: The Sontaran Stratagem)
