21. Winchester Mystery House
They say revenge is a dish best served cold, and the Winchester Mystery House is a testament to that. The property, located in South Winchester Boulevard in San Jose, CA was built by William Wirt Winchester for his wife, Sarah Winchester. It has gone on to be a famous place for its many architectural curiosities and its impressive gun collection. But what’s more interesting (and scary) is the fact that Sarah and many of the house’s inhabitants are visited by ghosts that have been killed by Winchester rifles!
