The Valtenesi saw the construction of several castles starting from the 13th century AD, some of which erected on the ruins of Roman forts. The tower of the castle in the center of Manerba represents the convergence point of a radial pattern that connects the towers of all the municipalities around. This is the oldest castle in the Valtenesi, built in the 12th/13th centuries on the ruins of a medieval fortress and of a settlement dating to the Iron Age, and is firmly anchored on the Manerba cliffs hanging over the southern basin of Lake Garda.
