Ancient Rome Built 190,000 Miles Of Roads And Researchers Just Traced Them All
An Aarhus-led research team has mapped 299,171 kilometers of Roman roads, revealing that the empire's most central overland path ran from Lepcis Magna through Antioch and Byzantium to Narbo. This network study challenges traditional assumptions by showing that provincial hubs played a major role in shaping the system, rather than every route strictly leading to Rome. Additional environmental impacts across Europe, including amphora waste, frontier earthworks, gold mining, farm fields, pollen, and seeds, demonstrate that Roman infrastructure reshaped hills and valleys far beyond the mapped road network itself.
