Beneath their canopy, a roughly circular earthwork persists, somewhere in the region of 44 metres north to south and 47 metres east to west, its interior sitting lower than the surrounding ground. That interior drop is the detail that matters. It suggests an enclosure, the general term for a ditched or embanked boundary, often prehistoric or early medieval in origin, that enclosed a settlement, a ritual site, or simply a territory someone once felt worth defining and defending.

The site appears as a woodland feature on the first edition Ordnance Survey six-inch map of 1839, which means it was already being treated as a distinct and bounded area at that point, rather than cleared farmland. By the 1900 edition of the same map series, surveyors marked it with a dashed line and hachuring running from the north-east round to the south-south-west, a cartographic way of indicating slope, consistent with the ground falling away from a raised perimeter toward the interior. The plantation that now covers it has, in an accidental way, preserved the earthwork's outline, the tree cover discouraging the kind of agricultural activity that levels such features elsewhere.
