The wall that defines this large enclosure at Coskeam, roughly 90 metres across its north-north-east to south-south-west axis, has long since grassed over, leaving little for a casual eye to catch at ground level. It took aerial imagery to make it legible again, the enclosure's outline emerging from above in photography taken between 2012 and 2018, where the slight rise and shadow of the buried stonework gives the circle away against the surrounding slope.

Enclosures of this kind are a recurring feature of the Irish countryside, typically interpreted as the remains of enclosed farmsteads or settlement areas from the early medieval period, though many remain undated without excavation. What makes the Coskeam example quietly interesting is its scale and its setting. The high ground of Termon rises to the west and Fahee North to the south-east, placing the enclosure in a sheltered valley position that would have offered both some protection and a useful aspect for farming. Recorded by Ros Ó Maoldúin and later compiled formally by Mary Tunney, the site also contains a hut site positioned just south of the enclosure's centre, suggesting this was once an organised domestic space rather than a simple boundary or field system. A hut site, in this context, refers to the surviving remains or hollow of a small dwelling, usually circular, that would once have sat within the larger enclosing wall.
