Built in 1865 for the Tiedemann family, Franklin Castle makes a spooky first impression with its sandstone exterior, round corner tower and gargoyle embellishments. Those who have
been inside the mansion, which is known locally as the most haunted house in Ohio, claim to have witnessed an eerie woman in black staring out the tower window, small children crying and strange happenings like doors flying off hinges and spinning lights. The possible cause? Four of the Tiedemann children died in the home, and owner Hannes Tiedemann was rumored to have killed his 13-year-old niece in a hidden passage and his mistress in the tower.
