The Cathedral of Cefalù was commissioned in 1131 by Sicilian King Roger II in homage to the Holy Savior, also known as Santissimo Salvatore, after the king found refuge from a storm on the shores of the town. The Duomo was built over subsequent years and centuries. Inside, its Byzantine-style mosaic of Christ Pantocrator is its most remarkable characteristic and probably the most significant reason why the structure was recently named as one part of the UNESCO World Heritage Site, Palermo’s Arab-Norman gems.
