Two of the faces of the baptismal font represent two series of 6 semi-circular arches. These faces are opposite each other. These arcatures are set between two flat bands. The arcatures are cut at the ends and all look the same, with the exception of the decoration on the capitals. The columns are composed of a bulbous base, a straight, slender shaft and a truncated cone-shaped capital with a decoration created by two flat leaves. The spandrels of the arcatures are decorated with a trifoliate palmette. There is a possibility that there were paintings of the apostles, one in each space between the columns.
This type of empty arcature frieze shows an influence from the Tournais tradition, but also from Namur. This series of arcatures can be seen, for example, on the vat in the church of Saint-Martin d'Antheit in the province of Liège, and also on the baptismal font in Beauvechain, in Walloon Brabant.
