The graveyard visible today measures only about twelve metres by eleven, modest enough to suggest a family burial plot. But the 1839 edition of the Ordnance Survey six-inch map tells a different story, marking the site as a circular enclosure roughly forty metres in diameter, with what appears to be a church building inside it. That earlier footprint dwarfs the surviving remains, and the circular form is itself significant: circular or sub-circular ecclesiastical enclosures are a well-recognised feature of early medieval Irish Christianity, typically marking the boundary of a sacred precinct around a church and its associated ground.

Two stone crosses survive within the walled section, catalogued separately as individual monuments. Their presence alongside the earlier cartographic evidence of a church building suggests this was once a site of some local religious importance, though no documentary record is attached to the name Kildoran here. The "Kil" prefix, from the Irish "cill", commonly denotes an early ecclesiastical site, often associated with a founder or patron saint whose name follows. Archaeological testing carried out in 2008 by McLoughlin, within thirty metres to the south and south-west of the graveyard, produced no archaeological material, which leaves the wider history of the enclosure's shrinkage and the fate of the church structure largely unresolved. What remains is a compact, masonry-walled plot, likely now in use as a family graveyard, set against the eastern foothills of the Blackstairs range.
