This Flamboyant-Gothic church contains fine furnishings. Note the 16C black and alabaster marble mausoleum by Corneille Floris (chancel), an altarpiece depicting St Dimpna's life (altar) and the 15C Brabantine altarpiece showing Passion scenes (right arm of the transept). The first ambulatory chapel houses a fine 14C altarpiece depicting the Twelve Apostles.
