The gothic nave has two doors.

The north gate located on San Saturnino street, is preceded by an atrium comprising several vaults with pointed arches. In its tympanum Christ the judge is represented and the capitals of the archivolts, where we come across scenes from the childhood of Jesus and the passion of Christ, exquisitely executed.

The other door, located on Campana street gives way to a large smooth thick stone wall crowned with a belfry.
