Winchester Mystery House

The Winchester Mystery House is a well-known California mansion that was under construction continuously for 38 years, and is reported to be haunted. It once was the personal residence of Sarah Winchester, the widow of gun magnate William Wirt Winchester, but is now a tourist attraction. Under Winchester's day-to-day guidance, its "from-the-ground-up" construction proceeded around-the-clock, without interruption, from 1884 until her death on September 5, 1922, at which time work immediately ceased. The cost for such constant building has been estimated at about US $5.5 million (if paid in 1922, this would be equivalent to almost $70 million in 2008 dollars).
