The interior of this spacious church has important works of art, including statues of the Apostles dating from 1774 on the pillars of the nave and the grave of Cardinal Mercier (1851- 1926), who opposed German occupation forces in the First World War, which can be seen in the left aisle near the Lady Chapel. In the Chapel of the Sacrament at the base of the tower is a communion bench by Artus Quellin the Younger and in the second chapel on the left weapons of the Knights of the Golden Fleece who in 1491 maintained a chapter of their order in Sint- Rombouts. In the transepts are several pictures dating from the 15th-16th C. including, on the right, the remarkable painting "Christ on the Cross" by Anton van Dyck (1627). The Baroque high altar (1665) of white marble was created by Luc Fayd'herbe, a citizen of Mechelen. In the choir ambulatory are four Baroque tombs of archbishops, including von Granville, and pictures from the life of St Rombout.
