This bizarre sprawling, 160-room mansion that took 38 years to build is the physical story of Sarah Winchester, heiress to the Winchester rifle fortune, and her continuous attempts to dodge evil spirits. She was told by a spiritualist in the 1880s she needed to continuously build the house to prevent being haunted by victims of the company’s guns. Inside are puzzling features, including staircases that go nowhere, windows set into floors and “decoy doors” to confuse the spirits. Guided and self-guided tours of the mansion are available, as well as a tour of the gardens and an ax-throwing experience in the stables. winchestermysteryhouse.com<
