The site is a rectangular enclosure measuring roughly 30 metres north to south and 55 metres east to west, with rounded corners, and it reveals itself not through upstanding earthworks but through a cropmark, the differential growth of crops above buried features that, from the air or in satellite imagery, traces the shape of something long buried beneath the topsoil.

The enclosure was identified by Simon Dowling, who spotted it in Google Earth imagery captured on 14 July 2018. Cropmarks of this kind typically appear in dry summers when parched vegetation thins over compacted ditches or banks, while lusher growth persists above the disturbed and moisture-retaining soil that fills a former cut. Rectangular enclosures with rounded corners of this scale are associated in Ireland with a range of periods and uses, from early medieval settlement enclosures to earlier agricultural or ceremonial sites, though without excavation it is impossible to assign this example to any particular era. A further detail caught in the same imagery is a field boundary extending south-west from the south-west angle of the enclosure, also visible only as a cropmark, suggesting that whatever activity shaped this landscape left more than one layer of trace.
