New Mapping Study Challenges the Classic Claim That All Roads Lead to Rome
A comprehensive analysis of roughly 190,000 miles of Roman roads shows that Rome was not the sole hub of the empire’s overland network, with Constantinople emerging as a more central node after the fourth century.
A team of scholars created a new, empire-wide map of the Roman road network by integrating data covering about 190,000 miles of routes in Europe, the Middle East and North Africa. Published in Nature Communications, the research led by Tom Brughmans of Aarhus University reveals that Rome was not uniquely central; instead, provincial capitals, particularly Constantinople, became the main overland hub after Emperor Constantine moved the imperial capital in the fourth century.
The analysis also points out that Roman Britain’s roads never led to Rome and that the empire’s maritime system was the dominant channel for trade. Historian Taco Terpstra of Northwestern University stresses that Rome retained its political, military and ideological primacy, but the study urges a more nuanced view of the ancient proverb. Additionally, the work confirms that Roman engineers built roads as straight as technology allowed, primarily for rapid troop movement before they gained economic importance.
Why it matters
The study reshapes our understanding of Roman infrastructure and challenges a long-standing metaphor about the empire’s connectivity.
