The old town of Avigliana is one of the most significant in Piedmont, for its medieval architecture and its churches. The castle was probably built in 942 by the Marqueses Arduinici of Turin (it was probably Arduino the Hairless who built the first settlement of Castrum Avilianae) on the top of Mount Pezzulano. This castle was used by the Counts of Savoy at least from 1137. In 1691, after conquering it, the French Marshal Catinat got it definitively demolished, leaving the remains we can see after a pleasant walk from Piazza Conte Rosso.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
