Alcide De Gasperi
The sewage network of the "castra" must have been extensive and would have followed the slope of the hill, discharging into the main sewer running under the "intervallum" in Alcide De Gasperi Street. The first stretch of this main sewer - 0.9 metres wide - was discovered in 1915–6 at the intersection of Alcide De Gasperi Street and San Francesco d'Assisi Street.
