The cathedral of Cefalù, name with which the Basilica Cathedral of the Transfiguration is known, is a minor basilica located in Cefalù, in the metropolitan city of Palermo, and cathedral of the homonymous diocese. According to the legend, it would have arisen following the vote to the Most Holy Savior by Roger II, who escaped a storm and landed on the beaches of the town. The real motivation seems rather political-military, given its character of fortitude. The construction events were complex and was finally completed in the Swabian age. An ambulacro obtained in the thickness of the wall and the same roof, made up of three roofs, of different epoch and construction technique, testify to the changes occurred in the project. The monument has a Romanesque style with Byzantine features.
