The Tower of London was built in 1087 by William the Conqueror in London. It was used as a prison from 1100 (Ranulf Flambard) until 1952 (Kray twins). The Tower is a complex of buildings in concentric circles of walls and a moat. It is believed to be haunted by multiple spirits from its past.
Anne Boleyn is said to roam the Tower of London following the same path she strode on the night before her execution.
