Château de Blanquefort is a ruined castle standing on a spur overlooking the Briolance valley. In the ninth century, a first fortification was built. The white stone gave the fort the name 'White Fort', in Latin Blanca Fortis, which evolved into the modern name Blanquefort. During the Plantagenet holding of Aquitaine, the fortifications were expanded into a royal fortress at the end of the thirteenth century by Edward I of England. At the end of the Hundred Years War, the fortress became French. A wine-producing village grew around the fortifications, probably worked predominantly by serfs.
Most of the buildings date from the Middle Ages, including a keep and gatehouse (13th century), a gun tower (15th century) and two lowered towers (12th and 13th centuries), incorporated into the house.
