The decoration of the spandrels is always different but has a common pattern. The first consists of a pair of palmettes segmented by ribbed and scalloped blades. The second is embossed, although a rounded motif can be seen at the tip. The third features a grey fruit surmounted by a double axial palmette and the last represents the head of a feline spitting out a cross as well as two palmettes on either side. These same types of palmettes spat out by the lion's head with the cross can be found at Termonde.
