St Rumbold's Cathedral was built in the thirteenth century. From the outset it was larger and more impressive than all the other parish churches and later on it became 'the church of the archbishops'. Originally there was a triple-nave cruciform church on the site of the vast cathedral. Only after a series of building campaigns did the church become a city's star attraction.
The inside of the cathedral is breathtaking. You can admire Anthony van Dyck's painting 'Christ on the Cross', along with works by (among others) Michel Coxcie, Gaspard de Crayer and Abraham Janssens. The real showpiece, however, has to be the high altar by Lucas Faydherbe which dates from 1665. https://toerisme.mechelen.be/en/st-rumbolds-cathedral
