Those hollows, known as cupmarks, are still there, cut into an outcropping rock in the garden of a private home at Kilcoe, their edges now softened by lichen and the slow work of millennia. Five of the twelve cupmarks are enclosed within a carved ring, a motif that recurs in prehistoric rock art across Atlantic Europe and whose precise meaning remains genuinely unknown.

Cupmark carvings of this kind are among the most widespread and least understood monuments of later prehistory in Ireland. They are typically associated with the Bronze Age, though dating them precisely is difficult since they leave no organic material for analysis and their surfaces accumulate weathering rather than context. What they meant to the people who made them, whether territorial markers, ritual sites, astronomical registers, or something else entirely, is a question that archaeology has not yet resolved. The Kilcoe example sits within a wider local concentration: a second panel of rock art lies roughly fifty metres to the south, suggesting that this particular stretch of ground held some significance for the communities who moved through it. The setting adds an interesting dimension; the rock faces out over Roaringwater Bay, with open water visible across a broad arc from east-south-east to west-south-west.
