The baptismal font, located in the Sint-Laurentiuskerk, is from the second half of the 12th century (1150–1160). It was made of Tournai stone by a Tournai sculptor's workshop with carved bas-reliefs on its four sides. The font bears strong similarities to, among others, the Romanesque font in Winchester Cathedral in England.
The reliefs depict the life of Saint Nicholas (the chalice legend, the three poor girls, and the three students) on three sides, and animals and soldiers on the fourth side.
