This church was built in stages, with the first parts completed in the late 14th century. The final stage was the tower, which was constructed between 1454 en 1463 and is commonly known as the Peperbus, a nickname it gained from it's resemblance to a pepper pot. The church was granted the title of basilica upon its 600 year anniversary in 1999. The 75m high tower is one of the main landmarks of the city and it's possible to climb the first part of the tower (236 stairs), to a height of 51 meters, which allows for great views over town. Entrance to the basilica is free, climbing the tower costs €2.50 for adults and €1 for kids, including an information leaflet.
