Ribadavia Castle, sitting at what is the unofficial entry point to the old town, has relics dating back as far as the 9th century, but the main structure was erected during the 15th century at the behest of the then Count of Ribadavia. It was abandoned in the 17th century when the counts moved to the palace adjacent to main square of Ribadavia.
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.
