It is a field boundary, modest in every physical dimension, yet quietly eloquent about the land it once organised.

The wall survives to a thickness of roughly 0.6 metres and a height of about 0.5 metres, its curvilinear course running north-east and then east for approximately 40 metres before terminating at a hut site. That association matters. A field boundary connected to a hut site suggests a small self-contained unit of settlement and agriculture, the kind of arrangement found across upland Ireland where communities once worked marginal ground that has long since been surrendered to bog. The collapse of the upper courses of the wall has spread along both sides of the base, which is typical of dry-stone construction left unattended over centuries; without maintenance, the upper stones migrate outward and downward, leaving the lower courses as the only reliable trace. The whole thing sits in rough hill pasture, overlooking a river valley below, on ground that would have demanded considerable effort to farm even at the best of times.
