There is no earthwork to speak of, no visible bank or ditch, no stone to catch the eye. The only evidence that anything is there at all comes from a single aerial photograph taken on the 16th of April 1974, in which the crop and soil patterns visible from above betrayed the outline of a roughly circular feature that the ground itself refuses to show.

Aerial photography has long been one of archaeology's more quietly remarkable tools. Buried or levelled features, invisible at ground level, can cast faint shadows in low light or produce differential crop growth over their outlines, and a photograph taken at exactly the right moment can preserve a trace that would otherwise be lost entirely. That is precisely what happened here. The 1974 image, taken by the Geological Survey of Ireland, captured what appears to be a circular enclosure, the kind of bounded settlement or farmstead that was common in early medieval Ireland. A slight curvilinear depression running roughly north-east to south-west is the only physical hint remaining, and even that is tentative. A cluster of related enclosures lies approximately 250 metres to the north-west, suggesting this part of Kilmore was once a more densely organised landscape than the smooth pasture now suggests.
