The dome of the cathedral of San Giorgio is a veritable work of art. Built in neoclassical style, it dominates the entire panorama of Ibla and at the intersection between the transept and the nave, rises up for just over 40 metres above street level.
The double segmental dome structure created by overlapping two layers of half spheres, rests on two rows of columns that were once free-standing and are now enclosed by windows that give it its now characteristic blue colour.
