What makes it worth pausing over is the asymmetry between its two faces: the exterior is built with a clean vertical face of large limestone blocks, while on the inside the stones are heaped in a slumped, banked profile, as though the wall was designed to present a different character depending on which side you approached from. The roughly circular enclosure, measuring approximately 32 metres north to south and 34 metres east to west, reads less like a field boundary and more like a deliberate statement of enclosure, though precisely what it was enclosing, and when, is a question the site does not answer easily.

Enclosures of this kind, sometimes referred to as cashels or ringforts depending on their construction and period, are among the most common archaeological monument types in Ireland, with an estimated 45,000 or more recorded across the country. They served variously as farmsteads, livestock enclosures, and defended homesteads, predominantly during the early medieval period, though some examples are earlier or later. The Stonehall example was recorded by Denis Power and uploaded to the national record in August 2011. The wall survives best along the arc running from the north-west through to the east-north-east, while the northern section has collapsed considerably. A gap measuring just over two metres wide at the east may represent an original entrance or a later breach. The interior slopes gently downward to the south and is covered in cultivation ridges aligned on an east-west axis, the kind of lazy-bed or ridge-and-furrow earthworks associated with small-scale tillage, possibly post-medieval in date.

The site sits in working pasture, so access depends on the landowner's permission, which is worth seeking before visiting. The position immediately below the brow of the hill means it is not visible from a distance until you are almost upon it, and the best-preserved section of walling rewards a slow circuit of the perimeter. The cultivation ridges inside are most legible in low winter or early morning light, when the slight undulations cast enough shadow to trace the pattern clearly across the sloping ground.
