A beautiful 19th-century Cistercian abbey built in a remarkable brick style. Don't hesitate to make a short detour to see it. The church and atrium are free to visit. It is closed on Tuesdays. A local produce shop is located at the entrance to the abbey, featuring cheeses and apple products made on the abbey farm—a great way to recharge your batteries!
