Fodor's Expert Review Duomo

Cefalù is dominated by a massive headland—la rocca—and a 12th-century Romanesque Duomo, which is one of the finest Norman cathedrals in Italy. Roger II began the church in 1131 as an offering of thanks for having been saved here from a shipwreck. Its mosaics rival those of Monreale. (Whereas Monreale's Byzantine Christ figure is an austere and powerful image, emphasizing Christ's divinity, the Cefalù Christ is softer, more compassionate, and more human.) At the Duomo you must be respectfully attired—no shorts or beachwear permitted. Private tours organized via  www.arabonormannaunesco.it can include tours of the roof and towers (€10).
