The current chapel of Our Lady was built in 1610-1683 to the site of earlier chapels dating back to 1527, 1373 and probably even 1183. The chapel was badly damaged by fire in 1910, but restored later. The massive front door represents Gothic style.
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.
