Set on a break of slope where the land drops away to the south-west, amid rough, undulating pasture full of rock outcrop and drainage channels, the place feels less like a tended churchyard than a field that has quietly accumulated centuries of use. The graveyard itself is a roughly trapezoidal shape, measuring about 65 metres north to south and 37 metres east to west, with the ruins of a medieval church occupying its northern quadrant. Among the headstones are a number of roughly cut stones dating from the mid-eighteenth century, alongside later nineteenth- and twentieth-century monuments.

The site's origins lie with Augustinian canons, the order of monks who established an ecclesiastical presence here during the twelfth or thirteenth century. By the time of the Royal Inquisition of 1568, it was recorded as the rectory of Twomahone, a name that no longer attaches to the place in any obvious way. What the Ordnance Survey Letters, compiled in the nineteenth century, noted about the graveyard was that it was not enclosed by any wall or mound, which is a striking detail: a large, active burial ground simply open to the surrounding pasture. The present post-and-wire fencing with a gateway on the west side is a much later addition. More intriguing still, an aerial photograph taken in 1973 revealed a large curving earthwork to the east of the church and graveyard. This arc in the ground is thought to be part of a wider ecclesiastical enclosure that originally surrounded the entire site, a common arrangement in early and medieval Irish church settlements where a roughly circular or curvilinear boundary defined sacred space from the secular landscape beyond.
