Set to open at the start of the 2014 season, Europa-Park is constructing an indoor attraction based on director Luc Besson's smash hit movie trilogy, Arthur and the Invisibles.

The Kingdom of the Invisibles will be housed in a 15m dome on an island surrounded by two streams and the Grimm's Enchanted Forest area.

At 3,500sq.m, this will be the German park's largest indoor attraction.

The centrepiece of the Kingdom of the Invisibles will be Arthur, a unique dark ride from Mack Rides, which will transport visitors through seven kingdoms in rotating cars suspended below a track during a 550m-long flight.

Other rides in the development will include a 10m tall poppy-shaped children's freefall tower and a carousel.
