The name derives from the presence of ancient fortified walls that in the early Middle Ages, surrounded the village and protected the castle. It is a municipality in the province of Cuneo, famous for the production of a fine Barolo wine and with an intense gastronomic tradition. The oldest part of the center, characterized by narrow and steep streets, is concentrated around the steeple of the parish of Santa Maria, whose existence was already attested in the XIII century, but demolished in the XX century. The Bell tower is what remains of the building, used as a watch tower, it was incorporated into the church in later ages and has undergone numerous renovations over the centuries.
The discovery of traces of settlements and other findings evidence that the center has been inhabited since the Neolithic Ages. In the later centuries also the Romans settled here. In 1028 the castle was attacked and captured by the troops of the Archbishop of Milan with the intention to stop the spreading of the anti-Catholic ideology of Cathar. In the XIII century it became a possession of the Marquis Del Carretto followed by the Scarampi. In the early XVIII century it became part of the Kingdom of the Savoy family.
