Unbaptised infants who died before receiving the sacrament were excluded from parish cemeteries well into the twentieth century, and the places where they were quietly laid instead, known in Irish as cillíní, tend to be older, repurposed sites already set apart from ordinary farmland. This enclosure near Whitehall fits that pattern exactly, and the Whitehall Roman Catholic Chapel sits only 180 metres to the east, a proximity that makes the separation all the more pointed.

The enclosure itself is substantial, roughly sub-triangular in shape and measuring approximately 100 metres north to south and 120 metres east to west. It is bounded by a well-preserved earthen bank, rising to about a metre in height, with a wide shallow external fosse, the term for a ditch that typically accompanies such banks. An entrance gap and causeway survive at the south-west. Inside, cultivation ridges run in two different orientations across the two halves of the interior, suggesting the ground was worked at different periods, and the remains of a ring-barrow, a low circular burial mound of probable prehistoric origin, are still visible in the eastern quadrant. A standing stone was recorded on the Ordnance Survey six-inch map of 1911 but leaves no visible trace today. The layering of uses here, prehistoric burial monument, later agricultural activity, and finally the cillín tradition, is characteristic of how these liminal spaces accumulated meaning across centuries.

By the 1930s, according to folklore gathered by schoolchildren in Castlepollard as part of the Irish Folklore Commission's Schools' Collection, the burial ground was no longer in use. That testimony, recorded by local children and their teachers, is itself a reminder of how recently this practice faded from living memory, and how much of what we know about it comes not from official records but from the careful writing-down of things that older neighbours still remembered.
