Essex's Roman Roads

A Lidar Re-appraisal

This is the first version of Essex's Roman Roads web pages and has been compiled by David Ratledge. As such I will probably have made several errors and missed some important information - please let me know. I will not be offended! With your help we can make this the best available resource for Essex.

The road numbering system is based on that devised by Ivan Margary over 60 years ago. Although long out of date it is still the best we have. However, some roads in Essex were unknown to Margary and therefore have no numbers.

Lidar, both 2D and 3D virtual reality models have been used extensively in appraising the alignment of the roads. This technique has proved an extremely efficient way of detecting linear feature such as Roman roads. 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 easily on the ground through traditional fieldwork. In addition other online and written sources have been consulted.

Road numbers are those allocated by Ivan Margary


Although our route map, on the face of it, looks very familiar some "new" roads have been added plus several gaps have been filled in together with refinements here and there.

The most important road hub by far is of course Colchester. Not all Colchester's road puzzles have been solved - the roads to the south-east and north are incomplete..

The south-east of the County is still a puzzle - perhaps more work is required here. It should also be pointed out the Romans would have exploited river and sea transport so the coastal area of the county would have also been served by boat.

Essex's Roman Roads

For all the known routes in detail choose the appropriate page:-

Coddenham - Colchester - Chelmsford - London, Margary 3

Coddenham - Colchester Just a few corrections to this largely known route to the important city of Camulodunum. A likely second route into Colchester too.

Colchester - Chelmsford Shares the first section with the Roman Road (Stane Street) to Braintree

Chelmsford - London Margary's Great Road. Mostly well determined but a new section suggested at Margaretting.

Stane Street - Colchester to Braughing, Margary 32

Colchester to Braintree Possibly two routes from the famous Balkerne Gate then very direct to the Roman settlement at Braintree

Braintree to Great Dunmow Stane Street continues on west of Braintree through Rayne to the Roman Settlement at Great Dunmow

Great Dunmow to Braughing, This final section of Stane Street is half in Essex and half in Herfordshire.

Other Roman Roads around Colchester

Colchester to Gosbecks - Kelvedon, Margary 320 This road looks obvious but evidence proving its existence is somewhat lacking.

Colchester to Lawford & Harwich Possibly a fort at Lawford plus this road had a branch off it to, almost certainly, Harwich.

Colchester to South-East Puzzling road(s) towards the coast but the Lidar evidence dries up.

Colchester to the North From the north gate one, probably two roads head northwards but to where?

Roman Roads around Harlow

Hobbs Cross to Harlow Often suggested and now we have the evidence and the route.

Harlow to Stane Street for Braughing, Margary 329 Margary recorded sections of this road and and we fill in the gaps and connect it to Harlow

Harlow to Bishop's Storford A logical road with not a lot of evidence

Great Chesterford - Great Dunmow - Chelmsford(?), Margary 300

Great Chesterford to Radwinter The route at Chesterford is a puzzle but from there on then it is pretty clear.

Radwinter to Great Dunmow North to south road and traceable all the way

Great Dunmow to Little Waltham (for Chelmsford) Almost certainly a Roman road but has several missing sections

Other Roman Roads

Wixoe to Braintree Newly Discovered Road

Wixoe to Radwinter A suspected road now fully traced.

Great Chesterford to Braughing, Margary 21, Very prominent in the Lidar data</p>

Braintree to Chelmsford, Margary 33a Two main alignment with a turn at Little Waltham

Great Dunmow to London, Margary 30 Virtually one long alignment heading for London.



Top of the list for thanks must go Colchester Archaeology Group and their Roman Roads Group led by Geoff Lunn. Thanks also. to Colchester Historic Environment Record (HER) and their online database and mapping. Local books I found particularly useful were Boudica to Raedwald by John Fairclough and Prehistoric & Roman Essex by James Kemble - see references below. Thanks are also due to Mike Aerts for developing his bespoke "MAGIC" Lidar software that turns numbers into 3D virtual reality models.

Mapping used is generally Ordnance Survey Opendata supplemented by Bing Mapping and Aerial Photography for selected areas. Google imagery has also been utilised.
