4. Six Flags New Orleans
Originally named “Jazzland” when it opened in 2000, the Six Flags company bought the park in 2002 and added popular attractions like Batman: The Ride. A water park was in the works, but then Hurricane Katrina struck in 2005 and the park was permanently closed. It is currently owned by the city of New Orleans, and while there is talk of transforming it into an outlet mall, it’s still an abandoned site. A photo essay can be found on Time.com.
