The larger of the two measures roughly fifty metres across, the smaller about twenty-six, and the smaller cuts into the northwest edge of the larger, suggesting the two were not built at the same time or for the same purpose. This kind of site is known through cropmarks, the phenomenon by which buried ditches, banks, or walls affect how crops or grass grow above them, producing patterns of differential colour and vigour that appear only under certain light or during dry spells, when the vegetation stress is greatest. They are, in a sense, the shadows of structures that may have long since vanished at ground level.

The site's history is genuinely obscure, in the most literal sense. When the Ordnance Survey of Ireland produced its first detailed six-inch maps in 1840, nothing was recorded here. A later edition, published in the Cassini series, does show a curving scarp approaching from the south-west, which hints that some above-ground trace survived into the nineteenth century, or at least was noted by later surveyors working from earlier observations. The circular form of the larger cropmark is consistent with a ringfort, the most common type of early medieval settlement monument in Ireland, typically a farmstead enclosed by one or more earthen banks and ditches. The intersecting smaller circle is harder to categorise without excavation, but the overlapping arrangement points to a sequence of activity across different periods.

The site sits in pasture, which both preserves and obscures it. Permanent grassland tends to protect buried archaeology better than arable fields, but it also makes cropmarks harder to read without specialist imagery. The clearest recorded evidence comes from a Digital Globe orthoimage captured between 2011 and 2013, with a fainter trace still discernible on Google Earth imagery from June 2018. Anyone with an interest in aerial archaeology can examine those public satellite layers directly, adjusting the date slider where available. On the ground, there may be little or nothing to see, though a slight unevenness in the pasture surface, particularly after dry weather, can sometimes hint at what lies beneath.
