Graffiti artist Banksy has announced the opening of a dystopian theme park in a British seaside town, featuring boats filled with migrants and an anarchist training camp.

The “Dismaland” theme park is located in a derelict outdoor swimming pool centre in Weston-super-Mare, a coastal town near Bristol in the west of England.

Visitors will be greeted by a burned-out version of the famous Disneyland castle, and a dead Cinderella hanging out of her crashed pumpkin carriage surrounded by paparazzi.

It features a riot van built to patrol the streets of Northern Ireland, altered to boast a brightly-coloured slide alongside its water cannon.

In one fairground game, visitors can steer miniature boats full of asylum seekers around a pond.

“I guess you’d say it’s a theme park whose big theme is theme parks should have bigger themes,” Banksy said in a statement on Thursday, describing the show as “a festival of art, amusements and entry-level anarchism”.

Spray paint, marker pens, knives and “legal representatives of the Walt Disney Corporation” are banned from the site.

The park also features works from artists from Israel, Palestine and Syria hand-picked by the elusive Banksy, who keeps his face and identity a secret and made his name with subversive graffiti, including some left in the ruins of homes in Gaza earlier this year.

Fellow artists in the exhibition include Britain’s Damien Hirst; Jenny Holzer, the first woman to represent the United States at the Venice Biennale; and pensioner Ed Hall, who has made trade union banners in his shed for four decades.

The development of the show was kept a strict secret before its official announcement, with local people told a cover story that the abandoned swimming area was being used in a film.

The exhibition opens this Saturday until September 27, and will feature performances from musicians including Russian feminist punk rockers Pussy Riot and England’s Massive Attack.
