The arrangement is what archaeologists call a boulder-burial, a Bronze Age monument type found mainly in south-west Ireland, in which an unusually large or distinctive boulder is propped above the ground on smaller stones, creating a low megalithic chamber. What makes this particular example quietly puzzling is that, for all its deliberate construction, it has yielded almost nothing in the way of answers.

When Dr W.F. O'Brien excavated the site in 1989, he found no burial pit, no human remains, and no associated finds. The monument appears to have been carefully placed, possibly ritually significant, and yet the ground beneath it offered no obvious evidence of the purpose it served. A pair of standing stones lies just 2.2 metres to the north-east, suggesting the site was once part of a small but intentional ceremonial grouping. The quartz conglomerate itself is worth noting: quartz was frequently used in prehistoric Ireland in contexts that seem to carry symbolic or ritual meaning, appearing at passage tombs and in votive deposits, though the precise significance attached to it remains debated. O Nualláin recorded the monument in 1978, and it was later included in the published Archaeological Inventory of County Cork.
