Dome - central nave
The interior of the Cathedral is solemn. There are five aisles (three in the transept) and two galleries overlooking the central nave. The columns supporting the round arches come from different places and belong to different times. In the middle of the nave, near the inner wall of the cathedral, is a long line of imposing granite colonnades, which are almost all antique and have capitals of Corinthian style. The women's gallery with little loggias is located above the nave.
