Seen from above, it traces the outline of a quarter-moon, an unusual form in a landscape where most ancient enclosures tend toward the circular or oval. It measures roughly forty metres along its northwest-to-southeast axis and about twenty-eight metres across, which puts it at a modest but deliberate scale, large enough to have served a meaningful purpose, whatever that purpose was.

The enclosure is defined in different ways on different sides, which gives it a quietly composite character. Along the northwest-to-southeast arc, the boundary is a scarped edge, meaning the ground has been cut away to create a slight but deliberate drop of around twenty centimetres on the outer face. To the south, a low linear bank, under two metres wide and just above knee-height on the interior, is accompanied by a shallow external fosse, the term for a ditch dug to reinforce a bank's defensive or boundary function. The western side is bordered not by a purpose-built feature but by a relic field bank, a remnant of an older agricultural boundary that was apparently incorporated into the enclosure's design. No original entrance survives in a recognisable form. The site is now overgrown with scrub, which makes it harder to read on the ground than the measurements alone might suggest.

What this enclosure was built for remains an open question. The combination of a scarped natural edge, a constructed bank-and-fosse on one side, and a reused field boundary on another points to something put together with practical intent, perhaps for settlement, stock management, or land division, but the evidence does not settle the matter. Its position on a terrace overlooking lower ground to the north suggests that aspect and visibility mattered to whoever laid it out.
