This historic abbey now houses a cultural centre, a secondary school and a seminary. The abbey, begun in the early 12C and often restored (by Cuypers in the 19C, for example), is lined by 17C and 18C buildings. On the west side, the façade is depicted by a massive tower-porch flanked by two square towers. The capitals in the nave are very varied. Those in the Romanesque crypt are quite remarkable.
