The west front of the cathedral measures 22 metres at its highest point. The lower, older, part is elaborately ornamented; the upper part contains only the
rose window, and was restored after the Turkish raid of 1566. In the lower part are seven blind arcades with double
mullioned windows, each different from the others, and decorated with
acanthus leaves and human figures. The central arcade, which is bigger than the others, has a
portal surrounded by small columns. The inscription in one of the
lunettes of the double window commemorates Stasio Grimaldi di Giovanni, who contributed financially to the building works of the cathedral. The cathedral has a
basilical ground plan, with three naves and three semicircular apses with piers on round bases. The interior has been returned to its original condition after lengthy restoration works between 1930 and 1969, which removed the
Baroque additions. ==Sources==
