Origin and history

The medieval castle of Pouancé, located in Ombrée d'Anjou in Pays de la Loire, is a 14th and 15th century fortress, classified as a historical monument since 1926. Located on a rocky spur overlooking the Saint-Aubin pond and the Verzee River, it was a key bastion of the Marches de Bretagne, competing with Châteaubriant. Its history is marked by recurrent conflicts between Anjou, Brittany and the Kingdom of France, especially during the Hundred Years' War and the Franco-Breton tensions of the 15th century.

The site, fortified from the 11th century, is mentioned for the first time between 1049 and 1060 in the Carbay cartular. In the 13th century, it became the center of a powerful seigneury, controlling Pouancé, Martigné, La Guerche and Segré. The lords of Pouancé, like William III, strengthen the fortress by creating the pond of Pouancé to protect its western facade. The seigneurial family declined in the 13th century, and the seigneurie passed into the hands of the Valois, then the Alençon, before being involved in the conflicts between France and Brittany.

Between the 14th and 15th centuries, the castle underwent major defensive modernizations: construction of the Grosse Tour by Pierre II de Valois (1371–1379), addition of mâchicoulis, and adaptation to firearms with sparrows, a caponière and a bastion. He was represented on several occasions (notably in 1379 by John IV of Brittany, in 1432 by John V, and in 1443 by the English), and played a central role in the wars between France and Brittany. In 1467 John II d'Alençon plotted there against Louis XI, resulting in the partial destruction of the fortress by the Bretons.

In the 16th century, the castle passed to the family of Cossé-Brissac, which kept it briefly as a stronghold during the Wars of Religion. After 1598, he lost his military role and became obsolete. In the 18th century, the ditches were filled, the chestnut destroyed, and houses settled in the high courtyard. Despite partial collapses (turn of the Moulin in 1915, Criminal Tower in 1936), excavations and restorations carried out since the 1960s by associations such as the C.H.A.M. have saved some of the remains.

Today, the castle of Pouancé is considered the "second fortress of Anjou" after Angers. Although partially in ruins, it retains remarkable elements such as the Heptagonale Tower, the Grosse Tour, the Sparrows, and the underground cooler. Open to the public in summer, it reflects the evolution of castral architecture between the Middle Ages and the Renaissance, as well as the geopolitical stakes of the Marches de Bretagne. Its potential inclusion in the UNESCO World Heritage Site, proposed in 2010, would underscore its historical and architectural importance.
