This is a real haunted house! Sarah Winchester, heir to the Winchester rifle fortune, was convinced by a psychic that all the people who had ever been killed by a Winchester gun would come back to haunt her unless she continually built a house. So she did, for 38 years – construction proceeded 24 hours a day from 1884 until she died in 1922. There are 160 bedrooms and 47 fireplaces over 24,000 square feet.
It has stairways going up to the ceiling, bizarre passageways and the infamous door to nowhere (it opens to a 13 foot drop). Creepy!
