The pasture looks ordinary enough, but beneath it, or rather where it once stood, was a circular enclosure roughly twenty-two metres across, clearly visible on the Ordnance Survey six-inch map of 1842, its interior marked as scrub land. Today there is no visible surface trace. The monument was quarried out of existence, its bank of earth and stone dismantled deliberately to supply building materials to whoever needed them at the time.

The site is possibly identifiable with a somewhat larger feature, around twenty-seven metres in diameter, known locally as An Cathairin, a diminutive Irish term meaning something like "the little fort", which carries in its name a folk memory of the earthwork's original character. This identification was recorded by Bowman in 1934, at which point the site was on land belonging to E. O'Connell. A ringfort, or rath, was typically a circular enclosure defined by one or more earthen banks and ditches, used in early medieval Ireland as a defended farmstead. This particular example may also have contained a souterrain, an underground stone-lined passage or chamber that would have served for storage or as a place of refuge, though no physical evidence of that feature now remains above ground either. The fate of An Cathairin is not unusual in the wider Irish landscape, where thousands of ringforts were quietly demolished across the eighteenth and nineteenth centuries, their banks offering a ready supply of stone and cleared ground more useful to a working farm than an ancient enclosure.
