This is the Winchester Mystery House. There is a lot of, well, mystery surrounding this house and I believe that this work captures a bit of that. There are many tales of ghosts and spirits wandering the house. And when touring the mansion, one can really see why there is such controversy surrounding it. What with the stairs leading to nowhere, doors that open into brick walls and a door that opens to a 30 ft drop, one can see why it would be viewed as haunted.
