Gaujiena Castle was built between 1236 and 1238. Severely damaged in 1702 during the Great Northern War, the structure was abandoned. Ruins can be viewed in the park near the 18th century manor centre.
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.
