The rise that marks the site today is so slight, barely eighteen metres across, that it reads less as a monument than as a hesitation in the landscape. Nothing announces what it is. The grass simply lifts, almost imperceptibly, and then levels off again.

The 1838 Ordnance Survey six-inch map recorded the site as an oval enclosure, roughly twenty metres east to west and fifteen metres north to south, which suggests a ringfort or similar early medieval earthwork of the kind once common across Ireland. By the time of the 1945 to 1946 revision, cartographers were describing it differently, as a small mound, and its recorded dimensions had contracted. Whatever structural definition it once possessed had already been fading for generations. The killeen within it adds another layer of meaning. A killeen, sometimes also spelled cillin, was an informal burial ground used for unbaptised infants, and occasionally for others considered outside the rites of the institutional church. These sites were often placed at the margins, on old raths or ringforts, beside boundaries, or at the edges of parishes, spaces already understood to be liminal. Here, the children's burial ground occupies the western half of the interior, a placement that seems deliberate rather than incidental, though what the original enclosure was used for, and how old it truly is, the ground has not yet given up.
