Arco, Trentino

The town is faced on one side by sheer limestone cliffs jutting up like a wall protecting it and its ancient hilltop castle.

Tourism is a major part of the local economy, with many Germans and Austrians coming over the Brenner Pass from Austria.

Popular tourist activities include windsurfing on nearby Lake Garda, and rock climbing on the walls near the city.

The annual Rock Master event, an international climbing competition, is held on the town's outdoor artificial wall.

Agriculture is also important, with vines and citrus orchards filling the valley opposite the castle.
