Chambers Mansion
If you're looking for a spooky spot in San Francisco, this is it. The gorgeous home was built for silver mine tycoon Richard Chambers, who lived there with his two nieces who notably hated each other. After he died, one of his nieces, Claudia, was found cut in half in the home. Some stories claim she was killed by an insane member of the family who was kept locked in the attic.
