The very fact of its classification tells us something: this is a place where the dead were laid to rest at some point in the past, distinct enough in character or location to warrant its own entry in the national record of monuments, yet still holding its details close.

Kilrush is a townland name with ecclesiastical resonance, derived from the Irish "Cill Rois", suggesting an early Christian foundation or enclosure associated with a promontory or wood. Burial sites in such townlands can range considerably in date and type, from prehistoric cist graves, in which a body was placed within a box-like arrangement of stone slabs, through early medieval Christian interments that sometimes accumulated around the ruins of a long-vanished church or chapel, to post-medieval unbaptised burial grounds known as cillíní, where infants and others excluded from consecrated ground were quietly interred. Without further detail, the specific nature of this particular site remains open, which is itself a reminder of how much of the Irish archaeological landscape is still being mapped, described, and understood.
