The castle was built by William the Conqueror and has been part of royal life and intrigue for nearly a thousand years.
The castle has a menagerie of royal ghosts. Henry VIII haunts the cloisters of the castle, announcing his presence his lumbering footsteps and the wheezing of his breath.
Charles I is said to haunt the Canons House, and George III haunts a small apartment where he was kept during his years of mental illness. His face has been seen peering from the room in which he was housed.
