Scattered across its earthen bank and within the enclosed interior are low upright stones, placed at intervals that suggest deliberate arrangement. Local tradition holds that these mark the graves of unbaptized children, giving a site already ancient an additional layer of sorrow and meaning.

The ringfort, or rath, is a type of enclosed circular settlement common across Ireland from the early medieval period, typically defined by one or more earthen banks and ditches. This one at Lecks appears to have been repurposed, at some point after its original use, as a burial ground for infants who had died without baptism. In Catholic practice, such children were long excluded from consecrated ground, and so communities found other places for them: old earthworks, liminal spots at field boundaries, or sites already felt to belong to an older, pre-Christian world. These informal cemeteries, sometimes called cillíní or killeens, are found across Ireland, and their presence within or beside ancient earthworks is not unusual. The association between the unbaptized dead and pre-Christian enclosures seems to have felt fitting, or at least permissible, to the communities who used them. At Lecks, the stones themselves are modest, low and upright, with no inscriptions recorded. Their number is not specified, but they occur both on the bank and within the interior of the rath, suggesting the space was used with some care over time.
