Perhaps Silicon Valley’s strangest and yet most enduring attraction is Winchester Mystery House, a 160-room Victorian mansion that was owned and built by Sarah Winchester, heiress to the Winchester fortune. Construction began on the house in 1884 and continued, almost nonstop, until 1922—racking up a bill of $5.5 million. Why the unending, breakneck pace? Because Sarah had been convinced by a medium that all the spirits of the people killed by Winchester firearms had placed a curse on her family and would haunt her forever unless she moved West and built a house to match their specifications, as revealed to her in séances.
Whether spirits gave her pointers or not, Sarah designed one heck of an oddball house. Guided tours let you ponder the heiress’s unusual designs, including doors that open onto blank walls and a stairway that leads straight into a ceiling. Other weird facts: the mansion has 52 skylights, 47 fireplaces, 40 bedrooms, 40 staircases, 13 bathrooms, 6 kitchens, 3 elevators, 2 basements, and 13 bathrooms but just one shower.
