 Today the castle is one of the best preserved fortresses of the 14th century.The castle is built on a site located on the frontier of the Frankish kingdom and that of Aquitaine (and later the lands of the French and English kingdoms) that has been fortified since the High Middle Ages and was once occupied by the Gallo-Romans.This location was thus strategically important, especially during the Hundred Years' War, and this can be attested to by its sizeable walls.
