It is an unremarkable-looking thing unless you know what it is, and it quietly anchors a site that turns out to be considerably more layered than it first appears. The graveyard at Dromkeen South is an L-shaped enclosure on elevated grassland, its rubble stone walls rising to 1.6 metres on the southern side, and within it sit not one but two ruined churches from entirely different centuries, standing close enough together that their histories are physically entangled.

The older of the two is a medieval church whose remains stand immediately south of the graveyard wall. A cross-slab, a flat stone carved with a cross that was a common early Christian grave marker, has been set into the top of the church's west wall, and other fragments of the medieval structure have been reused directly as gravemarkers elsewhere in the enclosure. The newer church is a Church of Ireland building erected in 1831, designed by the architect James Pain and funded by a gift of £900 from the Board of First Fruits, a body that financed Protestant church construction across Ireland in the eighteenth and nineteenth centuries. Samuel Lewis, writing in 1837, described it as a cruciform structure with an octagonal tower embattled and crowned with pinnacles. When this church was built, the graveyard boundary was extended southward to accommodate it, which is why the enclosure takes its current L-shape. The earlier, pre-extension graveyard, a rectangular area of roughly 24 by 14 metres, is still readable on the ground: a low scarp defines its eastern and southern edges, and the majority of the post-1700 memorials are concentrated within it.

The site sits roughly 170 metres south-west of Dromkeen House and its associated castle, and the elevated position means the surrounding landscape is visible from the graveyard. The Church of Ireland church now stands as a ruin in the southern quadrant of the enclosure, in an area that saw very few burials, which gives that part of the site an oddly sparse quality compared to the older northern section. The stone stile beside the entrance gate on the north wall is the most straightforward way in. The scarp marking the original graveyard boundary is subtle and worth looking for along the eastern and southern interior edges once you are inside.
