Measuring roughly four metres across, it is defined by a fosse, that is, a shallow encircling ditch, which is best preserved on its western side where it was cut directly into the hillslope. The whole thing is barely ankle-deep at its most pronounced, between five and twelve centimetres, and yet its near-perfect circularity marks it out as deliberate, purposeful, and very old.

This is a ditch-barrow, a prehistoric funerary monument type in which the defining feature is the encircling ditch rather than any significant raised mound above it. The site was not identified from ground survey alone; aerial photographs were instrumental in revealing its ring-ditch form, the circular cropmark or soilmark pattern that such monuments characteristically leave when seen from above. It does not sit in isolation. A second ditch-barrow lies just seven metres to the north-east, and a ring-barrow, a related but distinct monument class in which a low earthen bank typically accompanies the ditch, is located roughly sixty-six metres to the north-west. This clustering is common in the Irish prehistoric landscape, where burial monuments of broadly similar date and type tend to accumulate in the same areas, suggesting that certain places held repeated ceremonial significance across generations. The Cork-Limerick Junction railway line passes approximately forty-five metres to the south-east, a reminder of how closely the industrial infrastructure of the nineteenth century was laid down alongside, and sometimes directly through, a much older ceremonial one. The fosse itself has been partially cut across by a later land drain running roughly east-west, a small but telling sign of how agricultural use has quietly reshaped the monument over time.
