Possible section of Roman fort wall at Newmarket Road (GC7), Great Chesterford (EHER 13974)

A watching brief on a contractor's trench in Newmarket Road observed and sketched a chalky pebbly horizon in two places below the modern road surface. They accord with the alignment of the 1st century Roman fort (EHER 4942).

1989. Watching brief. A watching brief on Newmarket Road; a contractor's trench was observed and a sample of stratigraphy sketched at two points between 'Fairacre' and the sewage pumping station (TL 5038 4333, and TL 5040 4329). Here a chalky, pebbly horizon was revealed at depths of between 2.5 and 4 feet below the modern road surface at the northern point and 1 and 2 feet at the southern point. It is not certain whether this is a man-made or a natural deposit, and further sightings, associated with finds are required. <1> See also <2>. Note: The mapped polygons in this record differ to the mapped location of the linked event record. The mapping in this record is of unknown origin and the degree to which it is accurate is therefore unknown. The mapping in the linked event record has been derived from the grid references given above and is situated approximately 20m to the west. It is not possible to say with certainty which mapped location is most accurate.
