The castle includes a large tower, which is thought to be the most ancient part of the construction; the rest of the body has similar features, and therefore it is likely that it was built in the same age.

[2] In the 15th century, the castle and the surrounding were owned by the marquis of Busca, whose heraldic symbols have been found in some rooms, under later plasterings.

The castle currently houses an ethnological museum with original furniture items from the 19th century, and rooms dedicated to Cavour's stay and to Italian wine production.

[3] The castle has a rectangular plan and a massive appearance, with a large keep, occupying a whole wing, and a U-shaped structure with a series of turrets: two square and two rounded, the latter, added in the 16th century, being pensile.

There are a series of rooms, one of which, called Sala delle Maschere ("Masques Hall"), has a ceiling decorated with 157 panels featuring coat of arms, animals and allegory images celebrating the marriage of Pietrino Falletti, who owned the castle in 1517.
