In the 12th century, when Pope Callixtus II channeled the Aqua Mariana through Porta Metronia, smuggling became widespread. Goods could easily be transported in barrels with the current, evading the customs duties marked by the Walls. A strong grate, a “ferratella,” was installed to curb smuggling, giving the street its name. In the early 20th century, arches along Via della Ferratella became shelters for the needy and migrants. Makeshift homes formed a degraded, malodorous village due to stagnant water from diverted irrigation channels. Between 1925-30, the area was rehabilitated, leveling the road and restoring the street’s ancient name, Via della Ferratella, which had previously applied to the main road later renamed Amba Aradam.
