Chiesa di San Nicolò Regale
Built in the first half of the twelfth century, it has a square plant with three apses and a dome set on a drum cube shape, typical of Arab-Norman qube. Inside there is a small altar, four central columns in addition to those collected in the corners of the three apses and an Islamic-inspired flooring, similar to St. Cataldo decorations in Palermo. Between the seventeenth and eighteenth century the building was adapted to Baroque canons, with octagonal plant and pitched roof. Only in the 80s Arab-Norman jewel regained its original character. Of special interest is underlying base, in which were found traces of Roman mosaics of the late Imperial age.
