It is not much to look at by conventional measures: the wall stands only half a metre high and is less than a metre thick, with large upright stones set at intervals along its length like irregular punctuation. But the curve itself is the telling detail. Straight walls follow property logic; curved ones tend to follow something older.

The wall extends from a nearby enclosure, running first to the north-west for around thirty-two metres before turning north for a further fifteen. Curvilinear field boundaries of this kind are often associated with early medieval or prehistoric land use, where enclosures and their attendant walls followed the rounded forms of a ringfort or a cashel rather than the rectilinear patterns of later agricultural improvement. A cashel is a stone-built ringfort, a type of enclosed farmstead that was widespread in early medieval Ireland, and the curved wall at Lehid appears to belong to precisely that tradition. What makes the setting stranger still is the presence, a short distance to the west, of a boulder-burial: a form of prehistoric monument in which a large capstone rests directly on the ground or on low supports, without the raised chamber of a more typical megalithic tomb. The clustering of these features, the enclosure, the wall, and the boulder-burial, in the same small area of bog-edge pasture suggests a landscape that has been meaningful to people across a very long span of time.
