A window built into the floor. Staircases leading to nowhere. Doors that open into blank walls. The Winchester Mansion is an architectural marvel like no other, full of unexplained mysteries and bizarre history. The 160-room mansion was built by Sarah Winchester, the widow of gun magnate William W. Winchester, in the late-1880s and was under continuous construction up until her death in 1922. The magnificent, maze-like home is shrouded in legends about its architectural oddities, including 47 fireplaces, 17 chimneys and countless dead ends. On this 65-minuted guided tour, you'll learn how Mrs. Winchester believed the house was haunted by those who'd been killed by her father-in-law's infamous Winchester Rifle, aka the Gun that Won the West. Your ticket also includes admission to the Victorian Gardens, the Historic Firearms Museum and the Specialty Gifts & Antique Products Museum.
