A single aerial photograph taken in July 1989 captured what is known as a cropmark, a phenomenon where buried features such as ditches or walls affect the growth of crops above them, causing subtle variations in colour and height that only become visible when viewed from altitude, particularly during dry summers when the differential is most pronounced. What the photograph revealed was the outline of a small circular enclosure defined by a fosse, essentially a ditch dug to demarcate or defend a bounded space.

Circular enclosures of this kind are among the most common archaeological features in the Irish landscape, ranging from prehistoric ring-ditches associated with burial to early medieval ringforts used as farmsteads. Without excavation, it is impossible to say with certainty which category this particular example belongs to, and no further investigation appears to have followed the original aerial observation. The enclosure exists, for now, as a shape in a photograph, a single frame from a summer flight that preserved something the ground had been quietly keeping to itself.
