When the first detailed six-inch maps of Ireland were being compiled, this earthwork went unrecorded, which raises a quiet question: was it already so reduced by then that it barely registered, or did it simply escape notice in the otherwise unremarkable lowland fields?

What survives is a D-shaped, flat-topped mound, a form that suggests deliberate construction rather than natural accumulation. At its base it measures roughly 24 metres across, narrowing to about 12 metres at the top, and it rises somewhere between 0.6 and 1.4 metres depending on where you measure, that variation itself a sign of the damage it has absorbed over time. The straight side of the D faces east, and there a north-south roadway has cut directly through it, slicing away the edge and leaving the truncated profile visible. Further into that same eastern section, material has been quarried out, hollowing part of the interior. D-shaped mounds of this kind are sometimes interpreted as platforms associated with early medieval or prehistoric activity, though without excavation the function of this particular example remains open. What is clear is that the combination of road-cutting and quarrying has steadily reduced something that was once considerably more substantial.
