It has no enclosing wall, no formal gate, and no monument to announce itself. What marks it out are the small limestone uprights scattered across its surface, quiet and irregular, each one standing for a child who could not, under Catholic practice as it was observed for centuries in Ireland, be buried in consecrated ground.

Places like this were known as cillíní, informal burial sites used for unbaptised infants, stillborn children, and occasionally others considered outside the bounds of the parish cemetery: suicides, strangers, the shipwrecked. The local name for this particular site is Creig na Leanbh, meaning roughly "the rock of the children", recorded by Tim Robinson in 1980. It lies in the area known as Ceathrú An Lisín, near the townland boundaries of Baile an Lisín and Móinín na Ruaige, and measures approximately twenty-five metres in each direction. The uprights are limestone, the native material of the Aran Islands, and their small scale reflects both the age of those buried and the unceremoniousness that attended these interments, performed quietly, often at night, by grieving families working outside official ritual.

The site sits within a landscape already dense with bare karst limestone, so the uprights do not immediately announce themselves as grave markers. That plainness is, in its own way, the point.
