That combination of careful documentation and fundamental mystery is fairly typical of Irish standing stones, prehistoric or early medieval upright stones erected singly across the landscape, whose functions remain debated. They may have marked boundaries, burial sites, or astronomical alignments, but the archaeology rarely settles the question.

The stone was recorded by O'Kelly in 1944 as a limestone pillar standing 4 feet 6 inches high, measuring 1 foot 3 inches by 10 inches at its base, and leaning considerably to the south. It sits at the base of the western part of Knockainy Hill, in the townland of Correenfeeradda. When Condit and Coyne returned to document it in 2004, the recorded height had decreased to 1.15 metres, with a roughly square base of 0.3 metres by 0.3 metres. The slight difference in measurements between the two surveys likely reflects changes in the ground level around the base, or variation in recording method, rather than any dramatic shift in the stone itself. What is consistent across both accounts is its location in a field to the south of the hill, alone in the agricultural landscape.

Knockainy Hill itself carries a weight of association in Irish mythology and folklore, being linked to the goddess Áine, and the area around it is dotted with archaeological features. Whether this particular stone connects to any of that wider ceremonial landscape is not recorded. To find it, the townland of Correenfeeradda is the starting point, and the stone sits in field ground at the hill's western base. Access across farmland should be approached with care, and it is worth bearing in mind that a stone leaning to the south and measuring little more than a metre above ground level can be easy to overlook among long grass or at the edge of a field boundary. The rectangular profile and limestone composition are the most reliable identifying features once you are close enough to look.
