This 15C Flamboyant Gothic building needs to be studied from a distance to appreciate its vertical lines; like an elegantly chiselled stone reliquary. The niches were given new statues in the 19C. Inside, several works by Constantin Meunier are exhibited in the waiting hall. Of the three linked rooms, the last two are richly decorated. Note Christ's Resurrection by O. Venius in the Louis XVI Room and the painted ceilings in the first-floor Gothic rooms.
