Nottoway Plantation

The biggest antebellum mansion in the South — 53,000 square feet, 40 rooms, 22 white columns. Built in 1859, it earned the nickname "White Castle of Louisiana" and landed on Discovery Channel's Ghost Lab.

Room 14 is notorious - the last private owner, Miss Odessa Owen, died there and never left. Female guests have fled after feeling cold hands on their necks in the shower or watching the bathtub jolt violently across the floor. A coachman who protected guests during Civil War attacks still mans the front entrance. His presence is felt, and bells ring with no one pulling them. In the carriage house, a young girl who died 150 years ago appears on security cameras, wandering the parking lot waiting for a ghostly driver.
