The site exists in the record as a cropmark, a phenomenon where buried features such as ditches or banks cause the crops growing above them to ripen or wither at a slightly different rate than the surrounding soil, tracing the outline of whatever lies beneath in faint bands of colour across a field. It is the kind of evidence that reminds you how much of Ireland's past is not gone but simply underground.

The enclosure came to light in an aerial photograph taken on 16 July 2006 by Michael Moore. The image shows a large circular form in a tillage field, and the date matters: mid-July is precisely when cropmarks tend to show most clearly, as the growing season reaches the point where differential soil moisture becomes visible in the crop itself. Whether the enclosure is prehistoric, early medieval, or something else entirely remains unknown without further investigation. Circular enclosures of this kind in Ireland span an enormous range of periods and purposes, from Bronze Age ceremonial sites to the ringforts, known in Irish as raths, that once served as defended farmsteads during the early medieval period.
