It measures just 14.5 metres in diameter, defined by a modest bank and an external fosse, which is simply a ditch dug around the perimeter. What makes it worth a second look is the interior: the ground within dips slightly, giving the surface a shallow, bowl-like profile. That subtle depression is what leads archaeologists to classify it, tentatively, as a ring-barrow.

A ring-barrow is a type of prehistoric funerary monument, typically consisting of a circular bank and ditch enclosing a burial, whether a mound, a flat area, or a slight hollow at the centre. They are generally associated with the Bronze Age, though the term covers a range of related forms, and the dished interior seen here is characteristic of the type. The qualification in how this site is described, that it "may be" a ring-barrow, is a reminder that surface appearance alone can only tell archaeologists so much. Without excavation, the precise nature and date of the monument remains open. The setting itself adds a layer of ambiguity; marshy, low-lying ground beside a watercourse is not the elevated, visually commanding location more commonly associated with prehistoric burial sites, which gives this particular earthwork a quieter, more ambiguous presence in the landscape.
