Here are pictures of a medieval themed amusement park in Japan called Utopia, which included water slides, a bunch of kiddie rides, a roller coaster, a haunted house, a huge Ferris wheel, and many various buildings. I had a hard time tracking down any information on why this park closed. It appears to have been open between 1987 (?) and closed in 2005.
In 2005, a lot of stuff was still left in the haunted house. Here are some great pictures
