These features, common across Ireland, typically consist of a roughly circular or oval area defined by an earthen bank and ditch, and they turn up in a remarkable variety of forms: some are the remains of ringforts where families lived and kept cattle during the early medieval period, others are burial enclosures, encircled ecclesiastical sites, or boundaries whose original purpose has become difficult to read. The fact that this one is recorded as a monument at all suggests something in the field caught an archaeologist's attention, whether a surviving bank, a cropmark visible from the air, or an anomaly in the ground that the surrounding farmland has not entirely swallowed.
