The Mason House Inn was built in 1846, and, like many old buildings, has a reputation for being haunted. People have reported the ghost of a young boy pulling on people’s clothing at night in room 5, the ghost of a man named Knapp who was murdered in room 7, and, in Room 8, people have seen a floating head. Guests have also reported seeing the ghost of an elderly woman in several of the 3rd-floor bedrooms. 21982 Hawk Dr., Keosauqua, IA.
