New Map Details Roman Road Networks
Researchers utilizing the Itiner-e map project are challenging historical myths about the Roman Empire's infrastructure. Recent studies of approximately 300,000 kilometers of routes across Europe and the Middle East show that Byzantium served as the best-connected urban center rather than Rome. And engineers balanced topography, budget, and imperial priorities rather than building strictly straight paths. In Roman Britain specifically, occupiers constructed a comprehensive network of paved trunk roads during nearly four centuries of occupation from 43 to 410 AD. These infrastructural achievements sat alongside aqueducts and a massive standing army as core imperial features.
Why it matters
The Itiner-e map represents the largest digital cartography project of Roman roads ever compiled. This dataset enables researchers to evaluate how ancient infrastructure compares with modern motorways and re-examine the true administrative hubs of the empire. Historical assumptions regarding legionary engineering and centralized connectivity continue to be revised through network science.
