The boundary sits at the upper limit of rough grazing land, precisely where the ground gives way to broken, craggy terrain, a location that tells its own quiet story about how far people once pushed cultivation into difficult upland country.

The wall itself is modest in its dimensions: roughly thirty metres long, about a metre and a half wide, and no more than forty centimetres high at its tallest point. It runs northwest to southeast and is built in a double line of large rocks, a construction method that suggests some care and permanence rather than a casual gathering of loose stones. Relict field boundaries of this kind, the word relict simply meaning surviving from an earlier period of use, are found across Irish uplands wherever agriculture retreated, often following famine, land abandonment, or the gradual encroachment of bog. This particular example lies to the east of Lough Narman, and was recorded in September 2013 by Tony Miller, who noted that the surrounding area of bog and rough grazing preserves the boundary in its collapsed but legible state.

What makes it worth a moment's attention is less the wall itself than what its position implies. Whoever built it was farming right up to the point where the land became genuinely unworkable, and the careful double-coursed construction suggests they expected it to last. The bog has since crept in, the rocks have settled and spread, but the line they made across the hillside is still there to read.
