The reason for that diminishment is not time alone: the cairn has been robbed in the modern era, its stones lifted and pressed into service as field wall material. The result is a monument that carries two stories simultaneously, one reaching back thousands of years and another rooted in the practical economics of Irish farming.

The cairn measures roughly 21 metres in diameter, making it a substantial structure. Kerbed cairns of this type were typically Bronze Age funerary monuments, built with an outer ring of upright stones, the kerb, to retain the body of the mound and define its boundary. Within this one, traces of internal cists or compartments survive, marked out by upright slabs. Cists are small stone-lined boxes or chambers, usually associated with burials, and their presence here suggests the site once served a ceremonial or sepulchral purpose. The cairn is not isolated: it forms part of a wider complex of prehistoric monuments on the same hillside, a concentration that hints at the significance this landscape once held. Some of the kerb stones on the northern and eastern sides have been displaced, so the outer edge of the monument is no longer fully legible, but enough remains to read its original shape and intent.
