The origins of the Castillo de la Yedra could be Muslims, possibly from the Almohad era. During the 11th and 12th centuries, the first fortress was built, but the current appearance was built by Christians during the 13th and 14th centuries and during the papacy of don Pedro Tenorio. The alcázar was built by the archbishops of Toledo at the end of the 14th century. There is a keep and a small parade ground that surround the alcazar.
Its construction was designed exclusively for military use as a palace of a feudal lord or small court of medieval monarch. That is why its architecture is sober, although compensated by the beauty of the topography of its location and the surrounding landscape.
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.
