The ground inside holds a scattering of set stones, placed without obvious pattern, each one marking a grave. The site at Lisheennageeha is a cillín, known locally by the initials CBG, or children's burial ground, and it belongs to a practice that persisted quietly in rural Ireland for centuries.

Cilліní were informal burial places used for unbaptised infants, and occasionally for others considered ineligible for consecrated ground under Catholic canon law. Because the Church held that baptism was necessary for salvation, children who died before the rite could be performed occupied an uncertain theological position, and their families were left to find other solutions. Marginal land, the boundaries of townlands, or the edges of older, pre-Christian burial sites were frequently chosen. The plot at Lisheennageeha measures roughly twenty-three metres on its north-northwest to south-southeast axis and about six metres across, an irregular shape that reflects the informal, undocumented nature of such burials. There are no headstones in the conventional sense, only the set stones placed directly into the earth, their arrangement suggesting individual graves rather than any collective monument.

The site sits in ordinary farmland, and there is nothing architectural or formally constructed about it beyond the earthen bank along its eastern side. That plainness is itself part of what makes it legible as a place of genuine feeling rather than official commemoration. The randomly placed stones, unremarked and uneven, are the only visible record of the small lives interred here.
