This is a ring barrow, a burial monument type associated with the Bronze Age, consisting of a central mound encircled by a ditch, known as a fosse, and an outer bank. The one at Raheen is modest in height but precise in its geometry: the mound measures just over twenty metres in diameter and rises roughly half a metre, while the surrounding bank, more substantial at around 1.35 metres on its outer face, completes a form that was once deliberately, carefully constructed.

The details recorded here give a quiet portrait of how ancient and agricultural Ireland have come to occupy the same ground over centuries. An entrance, about two metres wide, opens to the east, with a causeway crossing the fosse so that the interior could be approached without descending into the ditch. A single rock sits in the middle of that entrance, aligned with the outer edge of the bank, its original significance unclear but its position too deliberate to be accidental. Elsewhere the monument shows the ordinary wear of a working landscape: the bank is denuded by cattle, rocks have been tipped into the fosse to the north, and a cattle gap has been cut through the western bank. Field boundaries of more recent date appear to have been grafted onto the barrow's north-eastern section, and cultivation ridges, the narrow parallel earthworks left by lazy-bed farming, are visible in the northern quadrant. About eighty metres to the north-east stands a limekiln, a small stone structure once used to burn limestone for agricultural lime, adding yet another layer of rural industry to this already layered corner of Kerry.
