An archaic architecture
Situated on the north-east corner of the inner ward, the keep is a rectangular tower of about twenty metres high, with walls about two metres thick. Four floors, three of which were vaulted, were accessed by a granite spiral staircase. In the 16th century, Rolland de Gourfaleur had openings created on the west and south flanks. The openings led to a balcony supported by a pair of large double corbels, still visible on the two sides.
Vue d'un ancien donjon en ruines avec des fenêtres et des arches visibles. La structure en pierre montre des signes de vieillissement et de détérioration, avec des parties manquantes et des surfaces érodées. Le donjon se dresse dans un paysage ouvert, entouré d'arbres et de végétation.
