Whether they served as mason marks, devotional scratches, or something else entirely remains unresolved, which gives the ruin a quietly puzzling quality beyond what the bare stonework might otherwise suggest. The church sits at the centre of a graveyard within an early ecclesiastical enclosure, the kind of roughly circular or oval boundary that in Ireland typically signals a foundation of considerable age, often pre-Norman.

The building itself measures approximately 16.6 metres east to west and 7.1 metres north to south, and its visible walls owe something to a reconstruction carried out by the Office of Public Works around 1979. Before that intervention, the scholar Power noted in 1932 that the north wall stood only a foot or two high, and the west wall was barely traceable at foundation level. What stands now reflects both medieval craft and twentieth-century consolidation. The architectural evidence points to a long building history: Leask, writing in 1955, placed the earlier parts of the church at around 1100 AD, while O'Keeffe in 1998 refined this further, dating the west end to the 11th century and identifying the eastern section as a 12th-century extension. That join is still legible in the fabric itself. Midway along the south wall, a clear break separates coursed sandstone to the west from uncoursed sandstone to the east, a seam in the masonry that effectively records the moment the building grew. The west wall retains antae, projecting corner pilasters characteristic of early Irish stone churches, and its central doorway once carried a rounded arch with an equal-armed cross in raised relief on the keystone; the voussoirs, the wedge-shaped stones that form the arch, have been re-set into the top of the wall. The east wall preserves a round-headed window with a chamfered surround and a fragment of hood moulding, and a reconstructed stone altar stands below it.

The church is a National Monument in State Guardianship. Visitors walking the site should look closely at the wall surfaces for those dolmen-shaped incisions, easily missed at a glance but worth seeking out once you know they are there.
