Just in time for Halloween, something very spooky has occurred at one of the spookiest places in the United States.

Rifle magnate William Wirt Winchester died in 1881, leaving behind his vast fortune to his wife, Sarah Winchester. Part of her windfall was allocated to building a Queen Anne-style mansion in San Jose, California. Around the time construction began in 1884, Winchester became deeply troubled and believed she was haunted by the ghosts of the countless individuals who had been killed by a Winchester rifle. And so, in an attempt to keep the ghosts at bay, Winchester insisted that the house should always be under some kind of construction.
Sarah Winchester died in 1922, and building finally stopped. Today, the house is more of a series of sprawling, connected, utterly nonsensical edifices with random hallways, doors to nowhere, random passages, 47 fireplaces, 40 staircases, 13 bathrooms, nine kitchens, 10,000 windows, and 160 rooms. Or, due to a recent discovery, 161 rooms.
The Winchester Mystery House, as it’s known, is a California state landmark, and with that designation comes a preservation team. This year, that crew found a room in the attic that was boarded up since 1906. Records indicate that Sarah Winchester was inside that room during the 1906 earthquake that devastated nearby San Francisco and its surroundings. Winchester became convinced that evil ghosts that were in the room with her had actually caused the earthquake, so she boarded them up inside the room before they could cause any more damage. All of the items have been removed from the room for a special exhibit at the Winchester Mystery House, suggesting that the forgotten attic area was Winchester’s sewing room: It contained a sewing machine, a dress form, paintings, a couch, and a pump organ.
Bonus: A movie starring Helen Mirren as Sarah Winchester is slated to hit theaters end of 2017.
