This church has a massive belfry nicknamed the "Pepperpot" due to its unusual shape. The interior includes superb keystones and stained-glass windows. The Flamboyant Gothic rood screen is the work of Mechelen sculptors. Note the south aisle's 15C stained-glass window depicting the Coronation of the Virgin Mary. A 17C repoussé silver reliquary contains relics of St Gommarus.
