Berlanga de Duero Castle, which is now in ruins, dates back to the 15th century though it was built over a 10th-century Muslim fortress of which there are no remnants. It originally belonged to the Tovar family who ordered the construction of the village’s collegiate. This castle played an important role, along with the defensive wall, in defending the villages along the Douro riverbanks during the Muslim Conquest. Of the remains that are left of the castle, it is worth noting the keep which is in very good condition.
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.
