Nicosia is a characteristic little mountain town and episcopal see in the interior of Sicily, with very ancient beginnings. In the Middle Ages Count Roger I built a Norman castle here - now in ruins - after he had defeated the Saracens. In 1535 Emperor Charles V visited Nicosía.
In the town center of Nicosia stands San Nicola Cathedral, with its original Gothic front, rose window, portal and bell-tower with twin and triple windows. The triple-aisled interior contains sculptures by Gagini, seating dating from 1622 and, in the chapel on the right, a 17th century crucifix by Fra Umile da Petralia.
The Dominican church of San Vincenzo Ferreri boasts a ceiling fresco of 1717 by the Flemish painter Guglielmo (Willelm) Borremans who worked in Sicily; it depicts the Holy Trinity crowning San Vincenzo Ferreri.
The church of Santa Maria Maggiore in Nicosia was built in the 13th century and rebuilt in Baroque style following damage by a landslide in 1757. It contains a marble polyptych by A. Gagini dated 1512, depicting the "Story of the Holy Virgin", and what is believed to be the throne of Charles V.
