The Perche region preserves an architectural heritage spanning from the Middle Ages to the classical period. Castles, churches, and abbeys in this Normandy area showcase the evolution of construction techniques and artistic styles from the 11th to the 18th century, influenced by Norman and Ligurian traditions. Medieval fortifications such as the Château de Bellême and Château de Senonches demonstrate the strategic role of this territory between the Duchy of Normandy and the kingdom of France. Religious buildings, including the Church of Saint-Céneri-le-Gérei with its Romanesque murals and the Notre-Dame of Mont Harou with its fortified tower, reflect the importance of monastic and parish life. Lords’ residences like Château de Montimer and Château de Frazé offer insights into residential architecture in Perche. The Perche Museum in Bellême and the Royal Military College Museum in Thiron-Gardais complete this exploration with collections related to regional history and military heritage.
