History
Château de Blanquefort is a medieval fortress in France, built initially by local lords in the eleventh century in the Romanesque style. It controlled the road through the Médoc north of Bordeaux and later became an English royal fortress in Aquitaine. The site also preserves evidence of human activity reaching back to the Bronze Age.
Prehistoric and Roman activity
People occupied the site around the twelfth century BC, during the Bronze Age. Excavations have recovered prehistoric pottery at the fortress and near the Jalle de Blanquefort, the river that crosses the surrounding marshland.
Roman activity is represented by numerous flat roof tiles built into the fortress foundations and by two coins bearing the image of Constantine the Great, a fourth-century Roman emperor. A modest Roman toll station or watchtower probably stood here to control the road linking Bordeaux with Noviomagus in the Médoc. The later fortress therefore occupied a position already connected with movement and supervision along an established route.
The medieval lordship
Blanquefort appears in written records at the beginning of the eleventh century. A charter dated 1028 to 1032 names Akelmus Willelm Affurt as the second lord of Blanquefort, while the cartulary of La Sauve-Majeure Abbey mentions the fortress in 1078 to 1080. During the eleventh century, a rectangular stone keep was built, making Blanquefort the oldest attested stone castle in Gironde.
The name Blanquefort probably derives from Blanqua fortis, meaning “white fort.” It may have referred to the pale limestone of the walls, which contrasted with the surrounding marshes. The seigneurial fortress controlled a major road and allowed its holder to collect and protect toll revenues. It also formed a defensive barrier against an enemy approaching from the north after landing in the Gironde estuary.
During the thirteenth century, the Blanquefort family became one of the most powerful families in Guyenne, the historical name for the broader Aquitaine region. Its lordship extended from the Garonne to the Atlantic Ocean and the Arcachon Basin. After the family died out for lack of heirs around 1250, Henry III and Edward I, kings of England and dukes of Aquitaine, acquired the castle and its lands in two purchases, made in 1254 and 1270 from Adelaide of Blanquefort and her husband, Bernard de Trancaléon. The English royal objective was to control river access to their regional capital.
English royal fortress
Under the Plantagenets, the English royal dynasty that held Aquitaine as well as the English crown, Blanquefort was expanded into a royal fortress. Edward of Woodstock, known as the Black Prince, stayed there while commanding Aquitaine at the beginning of the Hundred Years’ War, the prolonged series of conflicts between the English and French crowns from the fourteenth to the fifteenth century. The association explains the local name “Black Prince’s Castle,” although that name is also used for other medieval buildings in the region.
In June 1308, Edward II transferred the lordship to Bertrand de Got, the nephew of Pope Clement V, to meet his debts. By inheritance, the lordship passed in 1325 to Aymeri de Durfort, lord of Duras. On All Saints’ Day in 1450, several thousand French and English combatants fought near the castle in the battle known as the Male Jornade. The occupants of the fortress do not appear to have taken part in the fighting.
French control and decline
Gaillard de Durfort, an English vassal, still held Blanquefort one month before Bordeaux fell on 19 October 1453. Antoine de Chabannes, Count of Dammartin, then received the fortress as a donation. Gaillard recovered it in 1476 after swearing loyalty to the French crown, and the Durfort family retained the castle until the French Revolution. It ceased to be a residence during the seventeenth century.
The fortress saw its last fighting during the Wars of Religion, the sixteenth-century civil and religious conflicts between Catholics and Protestants in France, after the Durfort-Duras family adopted Protestantism. The family later became involved in the Fronde, a series of rebellions against the French crown from 1648 to 1653. After the Fronde, Cardinal Mazarin, chief minister to the young Louis XIV, ordered the crenellations demolished. The drainage of the marshes also removed the castle’s principal natural defense, while the development of Vauban’s artillery citadels made the older fortress obsolete.
A fire during the second half of the seventeenth century led to the castle’s abandonment. During the French Revolution, it was confiscated as national property and sold to a contractor, who exploited the buildings as a stone quarry. This process produced the ruined state visible today.
Protection and archaeological investigation
Château de Blanquefort was classified as a French historic monument in 1862 on the recommendation of Prosper Mérimée. It is privately owned. The first archaeological project began in 1962, followed by five campaigns between 1966 and 1975 and continuing safeguarding and restoration work. These investigations revealed occupation from prehistoric times through the modern period and recovered substantial archaeological material.
Remains
Château de Blanquefort stands about one kilometre south of Blanquefort on a natural rocky outcrop of soft sedimentary rock called molasse. The outcrop forms an island within a broad marshy plain crossed by the Jalle de Blanquefort, which flows onward into the Garonne downstream from Bordeaux. The fortress developed on this restricted high point, with its buildings and defenses adapted to the limited area available.
Eleventh-century core
Stone keep
The earliest castle consisted of a strong rectangular keep measuring approximately 18 by 11 metres. A keep was the principal fortified tower of a castle. Built in the eleventh century in a Norman Romanesque style, it used small rubble masonry, parts of which survive. A wooden palisade surrounded the keep, and a moat was probably dug around it. The compact arrangement formed the first durable stone defense on the rocky outcrop.
Royal expansion
Towers and enclosing wall
At the end of the thirteenth century, the English king-dukes doubled the area of the keep by adding six circular towers. These towers formed a summit terrace, while a stone enclosing wall replaced the earlier wooden palisade. The towers did not rise above the connecting walls, creating one continuous level for defense and circulation. Because the outcrop was small, two underground rooms were excavated beneath the courtyard for storage.
Entrance defenses
A small barbican, an outer defensive work protecting an entrance, stood before the drawbridge and controlled the road. The ancient straight Roman road may have been diverted during the expansion so that it passed around the castle rather than close to the keep. The fortress could accommodate approximately twenty to thirty English soldiers permanently, with the royal or seigneurial household staying there when required.
Artillery modifications
Later defenses and access
After the Hundred Years’ War, Charles VII adapted the castle for artillery. A new enclosing wall surrounded the summit and incorporated artillery towers, while gun ports were cut into the positions of earlier arrow slits. One tower became a stair tower with a monumental entrance, replacing the concealed access used in the medieval period. A gable above the entrance carried the arms of the Durfort-Duras family until the heraldic carving was hammered away during the French Revolution.
Archaeological remains
Objects and building evidence
Archaeological work has recovered pottery dating from the prehistoric period to the present. The finds include colored luxury glass, dozens of artillery projectiles including cannon shot, other weapons, bone needles, gold rings, and spindle whorls. Several dozen coins range from the Late Roman Empire to the reign of Louis XIV, including examples associated with Eleanor of Aquitaine and pieces from Spain, France, England, and Germany.
Pavement tiles and later occupation
The site has an exceptional collection of fourteenth-century pavement tiles, described as among the richest collections of its kind in France. A house of medieval origin was rehabilitated around 1900 to accommodate tenant farmers, adding a later phase of use to the surviving archaeological record.
