The Winchester Mystery House, a Victorian mansion located in San Jose, California, is a popular local tourist attraction for understandable reason. Construction began in 1884 and did not entirely subside until the death of its owner, Sarah Winchester, in 1922. Sarah's labyrinthine home, built following the passing of her rifle manufacturer husband William and infant daughter, was and remains a quirky architectural marvel, full of curious rooms, hidden passageways, staircases leading to dead ends, and well over 160 rooms in all. It now stands four stories, but prior to the 1906 earthquake it was nearly twice the size and stood a whopping seven floors. This is an optimally spooky place in which to set a film, but not the plodding, decidedly exploitative one "Winchester" has turned out to be.
