It measures roughly six metres across, defined by a fosse, the term for a deliberate encircling ditch, that is just wide enough and deep enough to have meant something, even if what exactly that something was has blurred across the centuries. The western side is the least preserved, where the ditch narrows slightly and the depth diminishes, but the overall form holds.

This is a ditch barrow, a type of funerary or ceremonial monument in which the defining feature is the encircling fosse rather than a raised mound at the centre. It sits on a naturally elevated patch of ground, the kind of slight rise in undulating farmland that would once have been deliberately chosen. The site was identified during a field survey carried out by Alison McQueen and Vera Rahilly on 2 February 2009. What makes its situation particularly interesting is the company it keeps: two ring-barrows lie within eight metres to the south and south-southwest, and a separate enclosure sits roughly eighty-five metres to the southwest. That clustering is not coincidental. Prehistoric communities returned to significant ground, and this corner of Shronell appears to have been one such place, layered with monuments that may span different periods and purposes. A farm trackway recorded on the 1906 Ordnance Survey six-inch map ran about thirteen metres to the east, suggesting the land was being worked long after any memory of the monument's original function had faded.
