The Onze-Lieve-Vrouwe-Kerk (Church of Our Lady) or simply the Grote Kerk (Big or Great Church) was built between 1285 and 1470 (rebuilt after a fire in 1457). The 65-meter tower contains a carillon with 67 bells including one weighing 9830 kilos, making it the heaviest bell in the Netherlands. Construction of the tower began in 1339. Inside the church are Renaissance choir-stalls made between 1538 and 1542 by a group of woodcarvers from the circle of Jan Terwen. Panels on the stalls depict allegorical processions in an antique style.
