There is no wall around it, no gate, no formal entrance. The site at Limehill is what is known in Ireland as a cillín, an informal burial ground used historically for those who could not be interred in consecrated ground, most often unbaptised infants. The exclusion of such children from the parish churchyard was a practice rooted in Catholic doctrine as it was applied in rural Ireland for centuries, and these quiet, unofficial plots, sometimes on townland boundaries or beside ancient water sources, became the quiet solution to an impossible grief.

The burial ground here covers a roughly rectangular area of approximately eighteen metres north to south and fourteen metres east to west. Rows of set stones running north to south mark graves that are themselves aligned east to west, in keeping with the broader Christian tradition of orienting the dead to face the rising sun. In the north-western corner, a small box-like plot defined by several set stones measures about 1.2 metres long and 0.5 metres wide, just large enough for an infant. What gives the site an additional layer of significance is its proximity to St Brendan's Well, which lies roughly fifteen metres to the south-southeast. Holy wells in Ireland were often sites of pre-Christian veneration absorbed into the Christian landscape, and the pairing of a cillín with a holy well is not unusual. The well's presence suggests this corner of the parish carried a particular sacred charge long before any church record was kept.

The site sits in ordinary farmland with no formal infrastructure around it, and the set stones that mark the graves are easy to overlook amid the grass. The small box grave in the north-western sector is the most clearly defined feature and gives some sense of the scale of the burials. St Brendan's Well nearby is worth seeking out as a companion feature, the two sites together offering a rare, undisturbed glimpse into how communities once managed the boundaries between the sacred, the marginal, and the lost.
