One of the most haunted houses in America, the frightening Franklin Castle can be found only in Cleveland, Ohio. Local legend has it that several murders were once committed here. Locals also report hearing strange noises and even seeing ghosts.
Built between 1875 and 1880, this foreboding three-story manse was constructed for the politician and newspaperman Frank Knox. The building was sold in 1928 and turned into a restaurant and hotel.
