The castle built on a 13th century fortification - is accessed via a steep climb starting from the small square where the ancient municipal building with loggia stood. Enfeoffed to the Doria family between the 14th and 16th centuries, the castle saw the succession of many families: Da Passano, Pallavicino, Serra, Spinola and Orsini Pio di Savoia. The guise in which it appears today dates back to the 18th century, when it was adapted by the Serra family into an elegant country residence. The castle, owned by the Doria family of Montaldeo since the beginning of the 19th century, has a complex structure in which the original structures survive, vestiges of previous use: the apparatus protruding on double brackets, the battlements and the configuration of the keep. One of the towers, which became an artist's studio in the last century and overlooks the surrounding landscape with large windows, offers a priceless view that sweeps over the Alpine chain, from Monviso to Monte Rosa, and over the Apennines, up to the Piacenza mountains
