The Val Petronio was colonized by Benedictine monks after the fall of the Western Roman Empire; later it became a possession of the Fieschi family who, in 1276, sold Castiglione to the Republic of Genoa. In 1747 the latter built here a series of fortifications against the Austrians. In 1815, after a short Napoleonic rule, it was acquired by the Kingdom of Sardinia-Piedmont, becoming part of the newly unified Kingdom of Italy in 1861.
