S.K. Pierce Mansion

Built in 1875 by wealthy furniture mogul Sylvester Knowlton Pierce, this Victorian home is a charming 26-room mansion—until it isn’t. Not for the faint of heart, the entities roaming the halls are “extremely advanced,” or so say hosts of Syfy’s Ghost Hunters and Travel Channel’s Ghost Adventures. Think voices, apparitions, moving furniture, slamming doors, sudden temperature changes and foul odors. Feeling brave? Rent the house overnight for a potential paranormal meet-and-greet—but you’ll have to sign a waiver first.
