Roughly circular, measuring approximately thirty metres north to south and twenty-six metres east to west, it was substantial enough in its time to leave a clear impression on cartographers across three separate surveys, yet by 1999 much of it had effectively vanished from view.

The site appears as a hachured feature, meaning it was marked with short lines indicating a raised or scarped earthwork, on both the first edition of the Ordnance Survey six-inch map from 1842 and on the later Cassini edition of 1920. The more detailed twenty-five-inch OS plan of 1897 offers the clearest picture, recording a short length of bank at the north-east, a scarp running from north-east around through east to south-south-west, and a counterscarp continuing the arc back around to the north-east. A scarp and counterscarp together suggest a deliberately constructed boundary, the ground cut or built up to define an interior space, of the kind associated with early medieval ringforts or enclosures used for settlement or livestock management. A later field boundary had been laid along part of the counterscarp between north-west and north-north-east, quietly absorbing the older line into the working agricultural landscape. When the site was inspected in 1999, the enclosing element across the northern and western arc had left no visible surface trace at all. What the maps had recorded so carefully across six decades of surveying had, in that portion at least, been swallowed by the pasture. Subsurface archaeological deposits, however, may well survive intact beneath the soil, meaning the enclosure is less gone than simply out of sight.
