It is not dramatic to look at, barely half a metre high in places and collapsed for much of its length, but what makes it quietly arresting is precisely this quality of partial submergence. The bog has swallowed a section of it whole, then released it again, and the wall simply continues on the other side as though nothing happened.

The structure traces an irregular course across the rough hill pasture at Coornacaragh in south-west Kerry. Beginning at a river bank, it runs roughly north-west to south-east for around 28 metres before turning north-east for approximately 50 metres. At that point it disappears beneath the bog for about 10 metres, re-emerges, and continues intermittently north-eastward for a further 36 metres or so before returning to the river bank. In plan it forms a rough enclosure, the kind of boundary that would once have divided grazeable land from something else, or kept animals from straying toward the water. It is built in drystone construction, meaning no mortar was used, just stone laid against stone, a technique common throughout Kerry and the wider west of Ireland for centuries. The wall as it survives is roughly 0.7 metres thick and stands about 0.45 metres above the bog surface where it protrudes. The bog itself is partly responsible for its preservation; waterlogged, oxygen-poor conditions slow the decay of organic and inorganic material alike, which is why the wall has not simply vanished into the hillside.
