Disney's own Treasure Island
flickr user Better Living Through Imagineering has some pretty good scans of the map given to visitors of Treasure Island. The island is in Bay Lake near The Magic Kingdom in Orlando. It is no longer open to the public. It was originally conceived as Blackbeard's Island, a pirate theme island adventure area. It was renamed Treasure Island and was to feature a number of attractions from the Treasure Island story. The project was expensive and kept getting scaled back. One feature that was built was the wreck of the Hispañola, a concept of which is below.
The island eventually became a bird sanctuary and was open to the public until 1999, when the birds and animals were relocated to Animal Kingdom and zoos.
Most recently, Jim Hill Media reports that there are now talks to reopen the island as a pirate themed attraction, owing mainly to the success of the Pirates of the Caribbean franchise.
