The site exists, at least for now, only as a cropmark, the kind of ghostly imprint that forms when buried earthworks or ditches cause the vegetation above them to grow differently from the surrounding soil, producing a pattern legible only at altitude and under the right conditions of light and season.

The enclosure came to notice through aerial imagery captured on 20 November 2005 and viewed via Google Earth, with the record compiled by Caimin O'Brien from details provided by Jean-Charles Caillère. Beyond its circular shape and approximate diameter, little else is currently documented. Circular enclosures of this kind are common across the Irish midlands and can represent a wide range of former uses, from early medieval ringforts, which were enclosed farmsteads typically surrounded by an earthen bank and ditch, to prehistoric settlements or ceremonial sites. Without excavation or further survey, Cooksborough's example sits in that ambiguous category of known but unclassified, its age and original purpose unresolved.

What the site illustrates, perhaps more than anything else, is how much of the Irish archaeological landscape remains submerged just below ordinary farmland, unregistered by any surface feature, perceptible only when the crop above it decides to tell a different story.
