5. Winchester Mystery House

A house doesn’t have to be haunted to be spooky and give you a case of the willies. Sarah Winchester (yes of the rifles dynasty) lost her family, and in determination to ensure her house wasn’t haunted by their ghosts concocted the most amazing blue print for her mansion. In the Winchester Mansion in San JosΓ©, which has 160 rooms and mile long hallways, there are doors that open on to brick walls and staircases that lead to ceilings and any number of secret passages. There are spider web motifs everywhere and various things themed around the number 13. Very weird.
