The Winchester Mystery House is a mansion in San Jose, California, that was once the personal residence of Sarah Winchester, the widow of firearm magnate William Wirt Winchester. Located at 525 South Winchester Blvd. in San Jose, the Queen Anne Style Victorian mansion is renowned for its size, its architectural curiosities, and its lack of any master building plan. It is a designated California historical landmark and is listed on the National Register of Historic Places. It is privately owned and serves as a tourist attraction.
Since its construction in 1886, the property and mansion were claimed by many to be haunted by the ghosts of those killed with Winchester rifles. Under Winchester’s day-to-day guidance, its “from-the-ground-up” construction proceeded around the clock, by some accounts, without interruption, until her death on September 5, 1922, at which time work immediately ceased. Sarah Winchester’s biographer, however, says that Winchester “routinely dismissed workers for months at a time ‘to take such rest as I might'” and notes that “this flies in the face of claims by today’s Mystery House proprietors that work at the ranch was ceaseless for thirty-eight years.
