The practical business of twentieth-century cartography quietly overlaid something far older, and for a long time the barrow beneath it drew little attention of its own.

A ring barrow is a burial monument of prehistoric date, typically consisting of a low central mound ringed by a fosse, or ditch, and sometimes an outer earthen bank. At Kilpatrick, earlier fieldwork recorded the central mound at roughly 18 metres in diameter, surrounded by a fosse about 3 metres wide. A possible outer bank was also noted, most visible along the north-east to east arc of the site, presenting more as a raised lip of the fosse than a distinct earthwork in its own right. A field fence running north to south cuts through the monument, removing the western section, though faint traces of the enclosure were still detectable in the adjacent field. About three-quarters of the site was considered to survive at the time of that earlier description, with the monument sitting on good pasture land with an open aspect, particularly to the north.

By the time a survey team visited in 2013, access was blocked by a high roadside fence. A partial view over it raised the concern that the monument may have been removed entirely since it was first recorded. Whether the mound still exists beneath the turf or has been levelled in the intervening years remains, for now, an open question.
