The largest church in Benelux and an important example of Brabantine Gothic architecture. Antwerp Cathedral also shelters four magnificent Rubens altarpieces. It has a three-bay choir with an ambulatory and five radiating chapels, a narrow transept of shallow projection and a nave with double aisles and side chapels, which is seven bays long including the façade block. There are a central lantern tower and two west towers. The church's one finished (north)spire is 123 metres (404 ft) high, the highest church tower in the Benelux.
