Britain's Roman Roads

A Lidar Re-appraisal

The last few years has seen a transformation in our understanding of the Roman road network largely as a consequence of LiDAR data becoming freely available. The use of LiDAR data (basically high precision height data) to reveal the course of Roman roads has been a great success throughout the country. Imagery derived from this data is often able to show clearly the surviving remains of the road agger, terraces, side ditches and cuttings, often where they cannot be identified on the ground through traditional fieldwork. Virtual reality 3D LiDAR models have been used extensively as these enable the viewer to look directly down the line of a road to trace its course. As a result lost roads have been found and many gaps and corrections have been made to the previously known roads. My thanks are due to Mike Aerts for developing bespoke software which has proved invaluable and has resulted in many discoveries..

The original version of these web pages went online over 20 years ago and covered just Lancashire. With the advent of LiDAR finding and tracing Roman Roads has become a much more efficient process and enabled the area now covered to include the whole of the North West of England and East Anglia too. Thanks are due to Neil Buckley for assisting me in compiling Cheshire's Roman roads.

I have taken a county based approach as this seems the most logical and easiest to understand. Historic Environment Records (HER) are generally organised on a county-wide basis too but with the exception of the National Parks which tend to have their own planning departments.

Earlier versions of some of these pages are available on the Roman Road Research Association's web site but the most up to date version are to be found here. I will attempt to keep updates as speedy as possible. So if you know something I have missed then please get in touch.
