Construction work on a new roller coaster at Gardaland theme park in Italy has started, with the ride set for a 2015 opening.

The as-yet-unnamed ride will be build by Switzerland-based Bollinger & Mabillard (B&M), which installed Raptor at Gardaland in 2011.

While the park is yet to give full details, it said the new roller coaster would offer an "unforgettable" experience.

Located in Castelnuovo del Garda in north-eastern Italy, Gardaland is the country's oldest theme park. The resort celebrates its 40th anniversary next year.
