The building was already a ruin four centuries ago, reported as such in 1615, yet the west gable still stands close to its original height, heavily overgrown and accompanied only by short stubs of the north and south walls. A splayed and lintelled window embrasure sits high in that gable, exactly where late-medieval church builders typically placed it, and what was once a doorway near the west end of the south wall is suggested by a straight ingoing in the surviving stonework, a deliberate threshold rather than a broken edge.

The original structure was no modest chapel. Ordnance Survey mapping from 1842 shows a rectangular footprint of roughly 38 metres east to west and 12 metres north to south, substantial dimensions for a rural parish church. The south wall, where it survives to full height, carries three inserted beam slots, with a fourth in the north-west corner; these indicate that a loft was added at some point after the church was first built, slotting timber beams into the masonry to create an upper level within the nave. The high window in the west gable and the position of the door are standard features of late-medieval ecclesiastical construction in Ireland, placing the building broadly within that tradition even without a precise foundation date. The north wall, by contrast, survives only 3.4 metres before it meets a tree that has since colonised the line of the building. The church appears on Ordnance Survey maps from 1842, 1905, and 1935, marked but never named, a visible presence in the landscape that the cartographers recorded without quite identifying.
