To the north of the tumulus around St Clare Road and St Clare Drive an extensive cemetery is attested by at least 14 contemporary flat cremation graves.<1> The evidence suggests that the Lexden tumulus is surrounded by an extensive urnfield.<2>

The core of the cemetery, measuring around 75m across with at least 27 cremation burials, is of a Late Iron Age date (CAR 6, 281; CAR 11, 164-169).

Later Roman burials, 1st century BC to the 3rd century AD, were then more widely scattered throughout the cemetery area (ibid). Outlying burials of the cemetery have been found elsewhere on St Clare Road (CAR 11, 164-9).
