In 1178, Ferdinand II of León donated the Ponferrada city to the Templar order for protecting the pilgrims on the Way of St. James who passed through El Bierzo in their road to Santiago de Compostela. Their castle was originally a hill-fort and later a Roman citadel. Templar knights took possession of the fortress and reinforced and extended it to use it as an inhabitable palace.
However, the Templars were only able to enjoy the use of their fortress for about twenty years before the order was disbanded and its properties confiscated in 1311. Several noble houses fought over the assets until Alfonso XI allotted them to the Count of Lemos in 1340. Finally the Catholic Monarchs incorporated Ponferrada and its castle into the Crown in 1486. Most of the walls were removed and used in local construction projects.
The building has an irregular square plan and the outstanding features are, above all, the entrance which involves crossing the moat on a drawbridge and, further on, two large towers with crenellations joined by an arch. Its twelve original towers reproduced the shapes of the constellations.

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.
