Just as the resort's most successful summer season in its history draws to a close, Europa-Park in Germany has announced the launch of a new major project: Arthur and the Invisibles.

The construction site for the largest and most elaborate indoor attraction in the theme park's history was recently opened with a symbolic ground-breaking ceremony earlier this month.

Set for a 2014 opening, Arthur and the Invisibles is an innovative new development by the internationally renowned manufacturer Mack Rides.

It will whisk visitors off into an incredible, highly detailed theme and experience world.

French film director Luc Besson, travelled from Paris especially to begin the construction work with the Mack family, which owns the theme park in Rust, south-western Germany.
