Among that fallen stone, though, the two pointed lancet windows that once lit the altar end remain largely legible, their heads, splays, sills, and some mouldings still intact. It is an odd inversion: the most architecturally refined part of the building survives better horizontal than it ever could have standing.

The church sits on a natural rise above the surrounding pasture, its position quietly elevated by centuries of burial activity beneath the graveyard. It appears in the Papal Taxation records around 1306 as "Kilmurre", and the name shifts across subsequent documents, appearing as "Kilmore" in 1471, "Killnorenon" in 1551, and finally "Kilmurry" in the Royal Visitation of 1615. By the time of the Civil Survey of 1654 to 1656, it was described as "a little Church roofed", standing on lands that in 1640 had belonged to one Hugh Neale. The building is constructed of roughly coursed rubble sandstone, though the lower courses are more carefully laid, and a base-batter, a sloped thickening at the foot of the wall designed to add stability, survives on the south side. The south wall exhibits a slight outward kick roughly halfway along its length, which may mark the boundary between nave and chancel or reflect two distinct phases of construction. This irregularity is invisible from inside, which makes its meaning all the harder to settle. The west gable, around 4.4 metres high, was already damaged by the 1840s: Ordnance Survey letters from that period record a breach in it roughly two metres wide and nearly three metres tall. A century later, a separate doorway had appeared in the same gable, likely cut to give access to burial vaults that were inserted into the western end of the church interior in the nineteenth century.

The interior accumulates several centuries of burial in a relatively small space. A late sixteenth or early seventeenth-century altar-tomb and a graveslab of similar date sit alongside five further graveslab fragments, and a substantial table-tomb dated 1793 occupies a central position near the north wall. A well-cut limestone corbel, the kind of bracket used to support a roof timber or stone feature, lies loose in the rubble at the north-east end, separated from whatever it once held up. The church has been partially reconstructed and repointed at various points, and the quoins at the north-west angle have been rebuilt to imitate cut limestone with punch-tooled dressing, a detail that sits slightly uneasily against the rougher original fabric around it.
