Joanna I of Naples
On the east face of the tower there are three carved crests under a hood mould. Although they are not clearly interpretable, the upper two are almost certainly those of the king of France and the Abbey of Saint-André. The third crest, which has what appears to be an oblique row of three roses, is probably that of Pope Clement VI who purchased the town of Avignon from Joanna I of Naples in 1348.
