The original use of the building that houses the Haunted Mansion was as a roller rink. The original roller rink was heavily damaged by a flood in 1972, but was able to be rebuilt. It turned into a Haunted Mansion after all the footers were in place. Nearly all sets and tricks were built in house, while "Pretzel" cars and tracks were purchased from the (now defunct) Rolling Green Park (Sunbury, PA) and West View Park (Pittsburgh, PA).
