The Haunted Mansion is the only Disney attraction to be placed in a different land in each park around the world. New Orleans Square, Liberty Square, Fantasyland, Frontierland and Mystic Point in HK when their version of the mansion opens in 2013. And with the exception of the one in Tokyo, they each have their own architecture that blends with their sorroundings.
