Archaeological Sites Castello del Conte Verde On a hill at the entrance of the Valle di Susa, between Mount Pirchiriano and Caprasio, are the remains of a castle. The oldest news not of the building but of a local defensive system would seem to be linked to the clash between the Franks and the Lombards, which took place at the Locks: probably also the relief of the castellazzo was provided of defensive structures that were part of it. Starting from the 13th century, the Castrum Capriarum was the center of one of the abbey Castellanies of San Giusto di Susa and was also the seat of court and prison. For this reason, it normally housed a small number of soldiers.
