The Cathedral (Santa Maria la Nova, 1539-1622). The façade was finished in the year 1840. The church has a late-Renaissance appearance that breaks the characteristic Baroque mold of most of the island of Sicily. Inside are frescoes by the Flemish painter Guglielmo Borremans, who worked here from 1722. Other works include a wooden Blessed Virgin draped in silver lamina (1760), a polychrome wooden statue by Stefano Li Volsi, and two marble statues portraying the Archangels Gabriel and Raphael. The Treasury houses a fine silver monstrance from the 15th century.
