The castle of the Rojas is located on the top of a hill near the town of Poza de la Sal. At the end of the 9th century Count Diego Rodríguez Porcelos repopulated Poza building the castle for the defense of the new territory. Like other castles of this time it may have been a simple keep surrounded by some walls.
In the 14th century Rodriguez de Rojas family rebuilt the current castle. It was occupied in 1808 by French troops and was a target of continuous attacks of Burgos garrisons until the end of the war.
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.
