The blue-tinted limestone abbey-church has a narrow chancel, which, strangely, faces west. The sobriety of the decor is reminiscent of the Cistercian spirit. The star-shaped vault rests on two limestone pillars. The church has a group of medieval sculptures, two of which (at the beginning of the nave) depict St Brigitte. The one on the right, The Ecstasy of St Brigitte, was famous among pilgrims. A 1459 triptych also shows the saint, and the reliquary behind the high altar dates from the time of his canonisation (1391).
