The castle overlooking the town, probably built on a Roman fort in defence of the barbarian invasions, was rebuilt in the communal period and reinforced in the fifteenth century, when it contained 120 houses and a church. Of the imposing building the walls remain, covered in the perimeter of the four towers and the tower entrance with the remains of a drawbridge. At the end of 19th century it was converted into barracks, functional until 1943. The recent recovery of the walls allows you to visit the walkway and to climb up to the tower entrance, which offers a splendid view of Lake Garda.
