The Orlando Wonder Works was built in 1998 to look like an upside-down building, complete with inverted palm trees. The story goes that a top-secret laboratory, located in the Bermuda Triangle, was carried by a tornado to this spot. It was built to appear to have landed on a 1930s brick warehouse. Wonder Works' interactive exhibits combine science with thrills and entertainment. The inside of the building is built to look upside-down as well. In 2006, this second location was built in Pigeon Forge. For more, see these websites: 1, 2, and 3.

Ripley's, just down the block from Wonder Works, was built earlier - in 1992. Ripley's building appear to be sinking into the street. Ripley's is now planning an upside-down building for its Majorca, Spain location. Wonder Works is also designing another one for Anaheim, CA. The Orlando Ripley's and Wonder Works were obviously influenced by the two biggest attractions in town: Disney World (built 1971) and Universal Studios (built 1990). Like their other 26 museum locations, this Ripley's Odditorium contains unique examples from Robert Ripley's 40 years of collecting travels. For more, see their website.

The Loony Bin is some sort of fun house. I believe this was built after the nearby "Top Secret" (see below). For more, see this website.
