A few small set stones are all that interrupt the tangle of vegetation, marking the rough outline of an unenclosed area roughly eight metres across. There is no wall, no gate, no inscription. To pass by without knowing would be entirely easy.

This is a cillín, the Irish term for an informal burial ground used, historically, for those who could not be interred in consecrated churchyard soil. Unbaptised infants made up the majority of those buried in such places, excluded by Catholic doctrine from the rites and ground reserved for the baptised. The practice was widespread across Ireland for centuries, persisting well into the twentieth century in rural areas. These sites tend to occupy marginal land, often near boundaries, water, or older, pre-Christian sacred spaces, places that existed somehow at the edge of the ordinary world. The Cuilsallagh site fits that pattern closely, sitting near a townland boundary in ordinary grassland, its dimensions modest and its presence almost entirely absorbed now by the vegetation around it.
