Château de Saint-Sauveur-le-Vicomte was built in the 11th and 12th centuries. It was besieged twice during the Hundred Years War. The city walls were breached by cannon in 1374. This is believed to have been among the first successful uses of guns against city walls in history. Today it is partially ruined, but still a notable castle with massive 14th century towers and a 12-15th century abbey.

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.
