Ancient Road Network Mapped

Researchers map 300,000 kilometers of Roman roads, challenging common historical assumptions.

Researchers have analyzed roughly 300,000 kilometers of Roman roads across Europe, North Africa, the Middle East and parts of western Asia, producing the most detailed reconstruction yet of the empire’s transportation network. The study challenges familiar assumptions: the roads were not uniformly straight, Rome was not the sole or most central destination, and modern travelers may overstate how much of the ancient network survives intact today. Roman engineers generally favored direct routes where terrain allowed, but mountains, valleys, rivers, settlements and available construction techniques shaped the network, often making roads less straight than modern highways. Cities including Constantinople, Byzantium and Ankara were in some respects more centrally positioned within the network than Rome. The roads linked military bases, cities, farms, rivers and sea routes, helping move troops, goods, people, diseases and ideas while supporting both imperial expansion and everyday local commerce.
