What it represents, though, is the faint but legible outline of an ancient enclosure, the kind of feature that survives in the Irish landscape precisely because the land around it has never been ploughed flat or built upon. It sits in the flood plain of a stream, in undulating terrain, and its dimensions are modest: roughly 14 metres north-northwest to south-southeast, and 12 metres west-northwest to east-southeast.

The site was recorded by Denis Power and uploaded to the archaeological record in August 2011. What defines the enclosure is a scarped edge, essentially a cut or trimmed slope in the ground, standing about a quarter of a metre high and roughly four metres wide. Beyond that, on the southern to northeastern arc, there is a faint trace of an external fosse, which is a shallow defensive or boundary ditch, here measuring around 25 centimetres deep and 8.5 metres wide. That fosse is largely concealed by yellow iris and rushes, the kind of damp-loving vegetation that tends to colonise low-lying ground where water lingers. The interior of the enclosure is mostly level, though there is a gentle indent along the eastern to southeastern edge. The overall impression is of something that time and seasonal flooding have done their best to erase, without quite managing it.

The site lies in Killaghteen, and access would be on foot across rough pasture, which in a flood plain setting means the ground can be soft or waterlogged depending on the season. Late summer or early autumn, when water levels are lower and vegetation has died back a little, would give the clearest sense of the earthwork's shape. The fosse in particular, smothered as it is in rushes, is easier to read when the surrounding ground is drier. There is no dramatic elevation or commanding view here; the interest is almost entirely at ground level, in the slight rise and fall of a field that has been quietly holding its shape for a very long time.
