What we know of it comes entirely from the air. Aerial photographs taken in July 1975 and again in July 1989 captured cropmarks, the faint differential growth patterns in vegetation that betray buried ditches and earthworks below the soil, revealing an irregular enclosure roughly a hundred metres north to south and fifty metres east to west. It is the kind of site that exists in the archaeological record as a shape rather than a place you can stand inside and comprehend.

The cropmarks trace the fosse, a defensive or boundary ditch, of an enclosure that sits against the western side of a field fence. At least one linear feature cuts across the interior on a north-west to south-east axis. More intriguingly, a pair of closely spaced linear fosses branches westward from the enclosure's western side, turns north-west and then curves back east to rejoin the enclosure at its north-west corner. At that junction, the inner of the two ditches briefly merges with the enclosure's own fosse before the pair diverges again and continues north-east until it disappears at a field boundary. Whether this arrangement represents an entrance funnel, a drove way for livestock, or something else entirely, the cropmarks alone cannot say. The eastern side of the enclosure may have been cut by a later field fence, meaning the original shape is likely incomplete. A separate circular enclosure sits in the north-west corner of the same field, suggesting the area accumulated activity over time rather than representing a single moment of construction.
