Winchester Mystery House, San Jose, CA
After the 1881 death of the owner of the Winchester firearms company, his widow, Sarah, used her huge inheritance to complete a home in San Jose. Until her death in 1922, she installed doors that went nowhere, stairs that led to the ceiling, secret rooms and other oddities, perhaps trying to escape the ghosts of those killed by Winchester guns. The Winchester Mystery House, as seen on Ghost Adventures, now features 160 rooms in a puzzling maze.
