That resemblance is not entirely misleading; the bank is stone-faced on its outer side in much the same manner as the surrounding field walls, which has likely helped it survive, absorbed into the working fabric of the farmland rather than standing out as something worth removing.

The enclosure measures roughly 34.5 metres east to west and 32 metres north to south, making it a fairly typical example of what archaeologists classify as a rath or ringfort, the most common type of early medieval monument in Ireland. These were enclosed farmsteads, usually dating from roughly the fifth to the twelfth centuries, where a single family or small community lived within a raised bank and ditch for reasons of status and security as much as defence. The bank here survives to an internal height of about 0.6 metres and an external height of 1.4 metres along its north-east to south-west arc, though the south-west to north-west section has been truncated by a road boundary, and the north-west to north-east stretch has been largely levelled, surviving only as a low rise in the ground. Locally the site is known as a lios, the Irish term for such an enclosure, a word that carries a folkloric weight too, since these circular earthworks were traditionally associated with the fairy world and often left untouched as a result.

The gentle east-facing slope on which it sits is characteristic of ringfort placement across Ireland, where an eastward orientation was frequently favoured, possibly for shelter or for catching morning light. The survival of the stone facing on the outer bank is a small but telling detail, suggesting that at some point the original earthwork was reinforced or repaired using stone, perhaps when the surrounding field system was being laid out and builders simply continued in the same style.
