Journées du Patrimoine 2026 : visites exceptionnelles à l'Abbaye de Royaumont
September 19
Asnières-sur-Oise
Medieval ruins & gardens








Wander through 800 years of history at this 13th-century Cistercian abbey, where Gothic cloisters and vaulted halls open onto seven hectares of remarkable gardens. The peaceful grounds include a medieval cloister garden, experimental kitchen garden, and the whimsical "garden of nine squares."
