The historic Windsor Castle in Britain has more than its fair share of ghosts, according to the United Kingdom-based Association for the Scientific Study of Anomalous Phenomena. The ghosts include some royal ones, including King Henry VIII, Queen Elizabeth I, King Charles I, and King George III (“Mad” King George). King Henry is supposed to haunt the cloisters near the Deanery with ghostly groans and the sound of dragging footsteps.
