It belongs to a category of site known as a cropmark enclosure, where buried ditches or banks, long since levelled by ploughing or natural decay, continue to influence the soil above them. Crops growing over a filled-in ditch tend to retain more moisture and grow taller or ripen more slowly than those around them, producing faint but discernible rings and lines that aerial photography can pick up under the right conditions.

This particular enclosure came to light through Google Earth imagery captured on 2 July 2018, when the seasonal contrast between the buried feature and the surrounding soil was sharp enough to reveal its outline. Circular enclosures of this kind are frequently associated with early medieval settlement in Ireland, typically taking the form of a ringfort, a type of enclosed farmstead used roughly between the fifth and twelfth centuries, though without excavation the date and function of any individual example can only be inferred. The site was identified by Seán Murray and recorded by Caimin O'Brien in April 2021. At approximately 36 metres in diameter, it falls within the smaller end of the typical ringfort size range, suggesting, tentatively, a single farmstead rather than a site of any particular status or complexity.
