Sauer Castle in Kansas City, KS, is considered haunted due to its long history of neglect and urban legends, with alleged ghostly occurrences including floating lights, voices, and shrieking noises associated with the house's tragic past and lingering spirits. The castle, built by Anthony Sauer, is said to be haunted by the spirits of Anton and his wife, whose suicide in the tower is a source of many local ghost stories. Reports of unexplained floating lights have been observed on the castle grounds and within the tower. Some claim to hear voices coming from within the deserted house, even when no one is there. People have reported hearing what they describe as shrieking sounds emanating from the castle, which others suggest might be the wind blowing through cracks in the windows. There are claims of seeing shadows and other apparitions in the castle, which some believe are the ghosts of Anton Sauer and his wife. Sauer Castle's haunted reputation is partly fueled by the sad story of Anthony Sauer's second wife, who reportedly took her own life by hanging herself in the tower after her husband's death.
