Origin and history

The castle of Gençay, located in Vienna in New Aquitaine, has undergone three major phases of construction. Its origin dates back to the late tenth century with a first castrum named Gentiacum, mentioned by the columnist Adémar de Chabannes around 993. This original castle, probably built to control an ancient path from Poitiers to Périgueux, was a strategic issue in local conflicts. Caught and dismantled in 993 by the Counts of the Marche, he was taken over by William the Great, Count of Poitiers, before being burned around 1025. In the 11th century, the seigneury of Gençay passed into the hands of the Rancon family, marking the beginning of a period of feudal rivalry.

In the 12th century, a second castle, the tower of Montcabré, was erected under the Rancon. Geoffroy II of Rancon, lord of Taillebourg, entrusted the guard to Guitard de Gençay. This castle played a role in the poitevin revolts against Henry II Plantagenet, king of England, notably in 1173, 1188 and 1194. In 1179 Richard Lion's Heart took the tower and had it dismantled, sealing its decline. These conflicts announced the first Hundred Years' War, opposing Capetians and Plantagenets for the control of the Aquitaine.

The third castle, called Du Guesclin, was rebuilt in the 13th century by Geoffroy V de Rancon, an ally of Louis IX (Saint Louis). The latter financially supported the work to strengthen royal authority in Poitou, a region disputed between France and England. The castle became a symbol of Capetian reconquest, but its history was marked by English occupations. In 1356, after the defeat of Poitiers, he was confiscated by the Prince of Wales and given to Adam Chel, a Welsh knight. He made it a base for plundering the region, even holding John II the Good prisoner. It was only in 1375, after a siege led by Du Guesclin and the Duke of Berry, that the castle returned to the French crown.

In the 15th century, the castle passed into the hands of the family of La Tremeille by the marriage of Georges de La Tremeille with Catherine de l'Île-Bouchard. He remained in this line until 1599, passing through the wars of Religion (speech by the Protestants in 1569) and gradually losing his strategic role. In the 17th century, with the priority given to coastal defence, the castle was neglected and then sold to the Brilhac family in 1655. After the Revolution, he served as a stone quarry before being classified as a historical monument in 1840 by Prosper Mérimée. Since 1969, excavations and restorations have preserved its remains.

Architecturally, the castle of Gençay is a 13th century defensive masterpiece. Built on a triangular rocky spur surrounded by ditches, it combines courtines, circular towers and a fortified entrance castle. The bas-fosse tower (24 m high) housed a seigneurial prison, while the Moulin tower illustrated both residential and military functions. The courtesines, 16 to 23 metres high, were pierced with archeries and hoarses, making the fortress almost impregnable. The interior courtyard, now extinct, once housed wooden and torchi domestic buildings, essential to seigneurial life.

Ranked among the first historical monuments of France in 1840, the castle of Gençay embodies feudal struggles and geopolitical issues of the Middle Ages. Its ruins, partially restored, offer a tangible testimony of the military techniques of the period and the Franco-English rivalries that shaped the history of the Poitou.
