Cathedral - Interior

The cathedral is like all Norman cathedrals in Sicily, a columned basilica with three aisles, forming the shape of a cross, with three apses and an open, brightly-colored roof truss. Its interior leaves a monumental impression: the arcades have pointed arches; the apse mosaics of the enthroned Christ are reconstructions, as are the apostle altars of the side aisles.

The sculpture depicting John the Baptist at the first altar is the work of A. Gagini (1525).
