Roman Road Network Revealed as Central to Empire, Not Rome

A new study published in Nature Communications has mapped the Roman Empire’s road system, covering roughly 190,000 miles (300,000 km) across Europe, the Middle East and North Africa. Researchers found that the old saying “all roads lead to Rome” is misleading; the empire’s later capital, Constantinople, was actually the most centrally located hub for overland travel. The analysis shows that provincial capitals such as Ankara, London and Corinth were strategically positioned on the roads, facilitating administration and tax collection. Roman engineers built durable routes using stone, lime cement and gravel, and many modern highways follow the same paths. The study highlights how the road network enabled the rapid movement of armies, goods, ideas and even diseases for more than two millennia.
