The earthwork, a rath being the Irish term for a roughly circular enclosure defined by a bank and ditch, used typically as a farmstead during the early medieval period, survives here as a low rise in the ground no more than 0.4 metres high on its outer face and a mere five centimetres on the interior. A faint depression curving from west-south-west to north-west is all that remains of what was once an external fosse, the defensive ditch that would have reinforced the enclosing bank.

What makes the site quietly compelling is how clearly the historical mapping traces its gradual disappearance. On the Ordnance Survey six-inch map of 1842, the enclosure was recorded as a hachured oval roughly 45 metres east to west and 30 metres north to south, already partially absorbed into the field fence system along its northern edge. By the 1937 revision, that oval had shrunk in the cartographers' rendering to a broken line enclosing a circular area of around 38 metres in diameter, sitting just south of an east-west field boundary that kinks noticeably to avoid cutting through the monument. The ground today measures approximately 34.7 metres east to west and 29.5 metres north to south, a modest contraction from the earlier surveys that speaks to continued erosion and agricultural encroachment over the intervening decades. The surrounding field fences have since been removed, leaving the site exposed in open pasture without even those later divisions to frame it.
