At the tip of the fortified spur of Crépy-en-Valois, the former Saint-Arnoul priory (founded in the 10th century, which became a Benedictine abbey and then an important Cluniac priory in 1076) suffered heavy damage during the Hundred Years' War, particularly during the sack of 1434. Of the church, the necropolis of the Counts of Valois, the western wall of the crypt and that of the north aisle remain, revealing a remarkable Romanesque vocabulary (acanthus leaf capitals, Carolingian traditions). Enhanced since 1964, the complex still retains the 12th-century stoker's room, the superb chapter house and the eastern gallery of the cloister.
