A commune in the upper valley of the Arroscia which extends over the southern slope of Monte Peso Grande (1092 meters or 3583 feet). Formerly a possession of the marchesi di Clavesana, it was ceded to the republic of Genoa in 1393. In 1402 it passed to the marquisate of Finale and subsequently to the Del Carretto of Zuccarello. It came back under Genoese rule in 1581, though with its own statutes. The ring of walls, on a polygonal plan with two large towers, comprise the ruins of the castle. The principal agricultural products are olives and wine.
