Researchers digitally reconstruct medieval England and Wales’ travel routes, revealing how Roman roads shaped post-Roman mobility over a thousand years.
A team of historians and digital archaeologists has unveiled a pioneering Geographic Information Systems (GIS) database that reconstructs travel and communication routes in medieval England and Wales — using the enigmatic Gough Map, a 15th-century cartographic artifact long shrouded in mystery.
Their work centers on the red lines etched into the Gough Map, which the team argues represent actual medieval roads and travel routes connecting towns, rivers, and regions across Britain. Far from being mere artistic flourishes, these lines now appear to be the earliest surviving representation of a complex overland route network in the British Isles.
By analyzing these lines through archaeological, linguistic, documentary, and environmental evidence, and comparing them with surviving Roman roads, the researchers reveal the deep and uneven legacy of Roman infrastructure in shaping post-Roman and medieval mobility.
Where Rome Ends and the Middle Ages Begin
The study dives into which parts of the Roman road system persisted, and why. Some regions, like the Thames Valley, saw Roman routes fade due to a shift toward river transport and geopolitical turmoil. In contrast, towns like London, Winchester, and Leicester, which retained their Roman urban cores, show a strong correlation between Gough Map routes and ancient Roman roads.
However, in places where Roman towns were abandoned or replaced, such as Old Sarum (later Salisbury) and Venta Icenorum (near modern Norwich), road continuity was weaker or vanished altogether. The researchers emphasize that no single factor explains this—road survival was a complex interplay of political, geological, economic, and highly localized human decisions.
From Red Lines to Digital Insights
This study builds on earlier digitization projects and delivers a new open-access GIS database that captures the Gough Map’s travel networks in digital form. More than a historical curiosity, the project demonstrates the potential of combining ancient maps with modern technology to uncover broad socio-economic patterns that influenced how people moved, traded, and interacted during the medieval period.
The approach also aligns with pan-European initiatives like Viabundus and Itiner-e, which aim to digitally reconstruct historical travel networks across borders. These collaborations promise to transform the study of mobility and infrastructure from antiquity through the early modern era.
A Thousand Years of Routes—and Decisions
Ultimately, this research reframes our understanding of medieval travel. The persistence of ancient routes wasn’t dictated solely by empire or economy but by countless micro-decisions made by people navigating their world — choosing paths based on soil, crops, politics, safety, and settlement.
In revealing how these decisions played out over centuries, the study not only recovers lost paths — it reconnects us to the lived geography of the past.
