The analysis of the documentation provided during the excavation of the Trajanic port in the ’80s led to a more accurate definition of both the chronology and function of the interventions realized inside the building in its late phases. Peculiar strategies of readjustment were set out from the early 4th until the late 6th centuries A.D., when the port was completely abandoned. The purpose of these operations was to contain floods and subdivide the cryptoporticus in several rooms, which were different by function and, probably, by tenants. Evidence of maintenance still persists even after the 5th century floods, as a sign that the structure maintained its function to keep receiving the imported goods, whose flow continued throughout the 6th century.
