The most haunted place in Britain! Situated somewhat uphill from central Hogsmeade, the ruined house is avoided by the villagers & Hogwarts ghosts too.The interior of the Shack bears evidence to a much more physical haunting than any ghosts are capable of.The Shrieking Shack is connected to Hogwarts by a secret passage that leads from under the base of the Whomping Willow to an opening in the floor of the main room downstairs.
