24. The two-nave

The two-nave, vaulted hall that was built in the 9th century between the apses of two basilicas – the Euphrasiana and the smaller, 5th-century church. That rooms between the two basilicas existed even before is indicated by the floor mosaics that were excavated in the midst of this area. At the end of the vaulted hall, there is a door with a marble-moulded frame, leading to the memorial chapel.
