Located in the middle of Bay Lake, Discovery Island, which is owned by Walt Disney World, has a long history going as far as the early-1900s, according to Abandoned Florida. The land was used for farming until the 1930s, later as the new landscape for Disney’s new attraction, Treasure Island; then it was a zoological park. Disney closed the park in 1999.
