Originally designed as a citadel, the Château de Montreuil-Bellay has a fascinating history. The château earned its reputation as impregnable because it withstood a siege by the Count of Anjou in the 12th century.

 In the 13th century, the château was used as a hunting lodge and hosted elaborate feasts. During the Hundred Years' War, peasants took refuge in the castle moat and neighboring monasteries. Later, when the Wars of Religion broke out, both the Catholics and Protestants turned to this location to refuel weapons and ammunition.

 By the late 15th century, the château served as a country manor estate instead of a fortress. As the castle's purpose changed throughout the centuries, the architecture evolved. The original austere fortress, with its 650 meters of ramparts and 13 defense towers, was transformed into a luxurious palace.

Open to the public for guided tours, the Château de Montreuil-Bellay gives tourists access to view two levels of the building: the cellars and the fully furnished rooms of the ground floor, including the Duchess of Longueville's bedroom; a well-preserved medieval kitchen; a beautifully decorated drawing room; a dining room with traditional beamed ceiling; and a small music room.

 The castle grounds include verdant gardens, filled with shady lime trees and fragrant roses. Also on the property is the 15th-century Collégiale Notre-Dame church, decorated with the coats of arms of the château's Lords.
