Lemp Mansion, St Louis, Missouri. Reputed to be one of the USA’s most haunted houses (if there are degrees of hauntedness). Charles Lemp committed suicide in the house in 1949, and ever since strange things have taken place at the house, including spontaneous door closing, breaking glasses, and an MTV reality TV show.
