Franklin Castle, Ohio City, is one of the most fascinating and most haunted houses in Cleveland. The four-story sandstone Gothic structure was built in the late 1880s and strange occurrences have plagued all of it's residents. Voices, organ playing, shaking light fixtures, and apparitions have all been reported. In 1975, the owner at the time went searching for the secret passageways ... and found more than he sought. He uncovered a human skeleton, deemed to be very old by the coroner.
