Roman road running from London to Great Dunmow (EHER 80682)

Roman road running from London to Great Dunmow.

NHRE import: Roman road, RR 30 (Margary) <1>, London-Great Dunmow. For full details including bibliography and OS field investigator comments see Ordnance Survey Linear Archive file (RR 30), held at NMRC. <2> Further investigations of the alignment of the road between Roundbush Green and Berwick Berners Hall utilising geophysics and fieldwalking has clarified the line of the road in some places. 25m south of the River Roding are strong magnetic anomalies, 10.5m apart, extending for 50m, and orientated 17 degrees east of north. There is clear evidence of an agger in this stretch of the road. It was noted that this was aligned with the section of road north of the River Roding, indicating that the dogleg aligning this section with the road south of Berwick Berners Hall, must be further south of this section. The crossing point of the River Roding hypothesised earlier was proven. The examined section has an average width of 8.16m, making it the fourth widest Roman road in Britain. Surveys to the north of the River Roding failed to locate evidence of the road. There is strong evidence of a settlement from 100 BC until at least the 5th century AD south of the river, as well as a Roman marching camp. A Roman signal station was located at TL 523 053 at 78m OD. <3>
