Origin and history

The priory of Château-l'Hermitage, affiliated with the order of Saint-Augustin, was founded in the 12th century thanks to the donations of Geoffroy Plantagenet, Count of Maine and Anjou. Its Prioral Church Notre-Dame, built in two countrysides (XIIe and XIIIe centuries), combines Romanesque elements (tower-clover of 42 m, northern chapel) and Gothic Angelvin (voûts on cross of warheads, nave basilical). The thick walls in red sandstone and the massive foothills reflect its defensive role during the Hundred Years' War, during which time the priory was fortified (grounded, archer) and disputed between French and English.

During the Hundred Years War (1356-1453), the priory, located between English Normandy and the valley of the Royal Loire, was burned three times and became a strategic stronghold alongside Sablé and Lavardin. Gilles de Rais and Jean de Bueil fought there, while Bertrand du Guesclin took part in the Battle of Pontvallain (1370). The convent buildings, rebuilt in the 17th century after the reform of the Augustins (congregation of France), housed a library of 2,800 books in 1790. The Revolution dispersed some of the property: only a wing of the cloister (classified in 1964), murals (15th-17th centuries), and carved stalls remained.

The Prioral Church, which became parish in 1842, retains exceptional furnishings: a 17th century confessional, classified statues (Vierge à l'Enfant, Saint Denis), and a fire sheltering the gissant of Marie du Bueil (15th century), sister of John V of Bueil. The murals, such as that of Saint Christophe (1606) or the Virgin of Mercy, illustrate the local devotion. The 18th century altarpiece, inspired by Poussin, and the stained glass windows complete this set. The priory, sold as a national property, was partially restored in the 20th century by private owners before its acquisition by the diocesan association of Le Mans in 2000.

The leading priors include René de Daillon du Lude (1590-1600), Bishop of Bayeux and Abbé Commandataire, whose coat of arms adorns the murals, and Gaspard de Daillon (1600-1632), king's adviser. The priory's income came from land (La Boissière), mills (Morançais), and seigneurial rights (grazing in the Berce forest). The archives also mention conflicts with Pontvallain priory for rye rents, reflecting its economic importance in Maine County.

The architecture of the priory combines religious and military functions: the northern chapel, equipped with mouths to fire for the naive artillery of the 15th century, side the still visible ditches. The convent buildings, rebuilt in 1680, adopted a sober style (white coats of the canons, cloister decorated with palm trees). The 18th century grid, separating Canons and Lay, was moved to enlarge the space of the faithful. Today, the site bears witness to this dual history, between Augustinian spirituality and strategic stakes of the Hundred Years War.
