Antonio Gambara is remembered for having created the central doorway of the Cathedral in 1426 and the southern portico a few years later. The latter, completed in 1453, thus after Gambara’s death in 1442, created a sort of link between the cathedral and the Cassaro level. In Gothic-Catalan style, it was commissioned by the archbishop Ubertino de Marinis and is characterised by the presence of three pointed arches, connected by three bays, surmounted by a median band and a tympanum with decorations.
