In 1675 the carillon comprised 35 bells, designed by Melchior de Haze of Antwerp. After the fire of 1741 this was replaced by a set of bells cast by Joris Dumery, 26 of which are still in use. There were 48 bells at the end of the 19th century, but today the bells number 47, together weighing about 27.5 tonnes.
