The larger of the two is a triangular slab of conglomerate, roughly a metre tall and a metre wide, oriented along an east-west axis. Immediately to its west, a smaller sandstone slab, standing about sixty centimetres high, emerges from the earth as though it were the first stone's quiet companion. Whether the two were ever intended as a pair, or whether the smaller slab is a later addition or a chance survival, is not recorded.

Standing stones are among the most enigmatic monuments in the Irish landscape. They date, in most cases, to the Bronze Age, though some may be earlier or later, and their purposes remain genuinely unclear. Some appear to mark boundaries, routeways, or burial sites; others seem oriented toward astronomical events. At Cappadine, the east-west alignment of the main stone at least invites that kind of speculation, though no excavation or detailed survey appears to have resolved the question. What gives the site an additional layer of interest is its proximity to a ringfort lying a short distance to the west. Ringforts, circular enclosures typically built of earthen banks or stone, were the farmsteads of early medieval Ireland, broadly from around the fifth to the twelfth century. Their appearance near much older monuments is common across the country, suggesting that early medieval people were as drawn to, and perhaps as puzzled by, prehistoric stonework as we are today.
