It is, by any ordinary measure, easy to miss, and yet it has been formally recorded as part of Ireland's archaeological heritage. That fact alone says something about how seriously the discipline takes even the most quietly diminished traces of human activity in the landscape.

When archaeologists Quinn and Carroll surveyed the area in 2010, as part of an assessment for a proposed wind farm, they described the wall as poorly preserved, oriented roughly north-north-west to south-south-east, and reduced to a single course of stones in a random linear arrangement. Field boundaries of this kind are common across rural Ireland, serving for centuries to divide pasture, mark ownership, or contain livestock, but most survive in considerably better condition. At just under a metre wide and half a metre tall at its highest point, this one sits at the very edge of legibility as a built structure rather than a natural scatter of rock.
