No headstones break the surface, no ruin marks the skyline, and the graves, if they are there at all, lie entirely beneath the grass.

The site sits within what is thought to be an early ecclesiastical enclosure, a roughly circular or oval boundary of the kind that typically surrounds early medieval Irish church sites, often pre-dating the arrival of formal stone architecture. In 1934, a local researcher named Bowman noted the tradition of a church and burial ground placed on a fort in land belonging to a P. J. O'Callaghan. The coincidence of a fort and a church in the same location is not unusual in Ireland; early communities frequently established religious sites within or beside pre-existing earthworks, borrowing both the physical enclosure and perhaps some older sense of significance attached to the ground. What makes Killarush slightly stranger is the approach. Bowman also recorded a disused road leading to the church site, known locally as Robber's Lane, a name that carries its own quiet unease. A narrow laneway visible on the 1842 Ordnance Survey six-inch map appears to run along the western side of the enclosure, and this may be the same track, its old name outlasting any memory of what the road was actually used for, or by whom.
