This large brick church was built around 1450. Today it is used as a venue for trade and cultural events. There is a peal of 51 bells in the tower. The church has three naves of equal height, roofed with a timber vault. In the choir, which was built around 1500, can be seen an admiral's tomb and the arms of knights of the Golden Fleece. There are some remarkable stained glass windows in the ambulatory, one of them representing a kneeling Emperor Charles V.
