Well, I am a San Jose Senorita, so here is a picture taken here in San Jose.
This is the Winchester Mystery House. Basically Sarah Winchester was a crazy old woman. Her husband made guns, the Winchester rifle. Her spiritual adviser told her that her house was haunted by people killed by her husband's rifle.
In order to appease those spirits, she would have to continue building the mansion for them. Therefore, the 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, about $70 Million today, ( Information from Wikipedia)
