Roman roads are found by combining old maps and written records, aerial and lidar surveys, cropmarks and traces on the ground such as straight lines, banks, footpaths and place names. Our map pulls those findings together as one network, but a line on it is a starting point.
Key takeaways
- Researchers combine written records, maps, excavation, aerial photographs, lidar and place evidence rather than relying on one clue.
- In Britain, surviving stretches are often footpaths, tracks or modern roads, and some are marked on Ordnance Survey maps.
- Only 2.7% of our road length is classed certain, so most lines on the map are best treated as a guide to search.
- Use the Near me button to find the closest roads, then check the ground and local records.
How Roman roads are found
No single clue finds a Roman road. Researchers build up a picture from several kinds of evidence, which is the same approach the Itiner-e atlas took across the empire: archaeological excavations and surveys, milestones, written sources such as itineraries, and the positions of Roman places [1]. This is also how you can look for them yourself.
Maps and records. In Britain, stretches of Roman road that survive as footpaths through woodland or common land are marked on Ordnance Survey maps with dotted lines. One example is the section of Stane Street in Eartham Wood, in the South Downs [2]. In many places Roman roads were built over in the eighteenth century to make turnpikes [2], so a modern road can follow a Roman line.
Straight lines. Roman engineers favoured direct routes, so a long, unusually straight road, hedge line or parish boundary can hint at a Roman road. It is a clue, not proof, because later roads can be straight too.
Aerial views. Crops grow differently over buried ditches and walls, which shows up from the air as cropmarks [4]. Lidar, a laser survey flown over the land, can reveal faint banks and ditches under woodland [3].
Place names. In Britain, many roads carry later names such as Watling Street, rather than Roman ones [2]. Names containing street or stone can be hints, but they are not reliable on their own.
Excavation. A cut across a suspected road, with its layers of stone and a camber, is the strongest proof. That is the work of archaeologists, not walkers.
An example from our data
Our map draws 299,171 km of roads, but only 2.7% is classed certain. The rest is a reconstruction from the methods above. In Britain, the United Kingdom page records 98.8% conjectured. The Stane Street page gives its length as 93.3 km, and Akeman Street as 119 km.
To find the nearest ones, press Near me on the map, or read Roman roads near me. The map lists the closest roads with distances. Treat each as a place to look, then compare with a printed guide or local historic environment record.
The thing people get wrong
People often expect a Roman road to look like a paved street. In most places it does not. Extant remains are often much degraded or hidden under later surfaces, and many sections have been ploughed over or stripped of stone [2]. What you find is more often a low bank, a field edge or a track. Please stay on public paths, respect private land, and report possible finds to the local archaeology service rather than digging.
Frequently asked questions
Can you still see Roman roads today?
Yes, in places. Some survive as footpaths through woodland or common land, and many are followed by modern roads, though lots have been ploughed away or built over.
How do I find the Roman roads near me?
Use the Near me button on the map. It lists the nearest roads with their distances, and you can then check each against a local record.
Are the lines on your map the exact Roman road?
Not exactly. Only 2.7% of the length is classed certain, and most of the rest is a best reconstruction.
