Chessington World of Adventures Resort is a theme park, zoo and hotel complex in Chessington, Greater London, England, around southwest of Central London. The complex opened as Chessington Zoo in 1931, with the theme park being developed alongside the zoo by The Tussauds Group and opening on 7 July 1987, as one of the first themed amusement parks in Britain. The theme park, which features over 40 rides, is now owned by Merlin Entertainments, following its merger with The Tussauds Group in 2007. Under Merlin, Chessington has been increasingly developed into a resort tourist destination, including two on-site hotels, a high ropes course and camp site.
