The rectangular structure measures just over fifteen and a half metres east to west internally, and a little under six metres across, and what little remains of its walls preserves a surprising amount of detail. A small stone trough, roughly half a metre by forty centimetres and thirty centimetres deep, is set directly into the inner face of the north wall. Its purpose is not entirely certain; such features in medieval Irish churches are sometimes associated with holy water, ritual washing, or the mixing of liturgical materials, though no specific function is recorded here. A chest tomb, the kind of raised box-shaped funerary monument common from the sixteenth century onwards, has been built along the western line of the south wall, suggesting the site continued to hold religious and social significance well after the building itself fell out of use.

The church belonged to the parish of Templeomalus, and according to a note recorded by Webster in 1932, it was "lately burned by accident" in 1615. That single phrase is the most vivid piece of documentary evidence attached to the site. Whether the fire brought about the end of regular worship here, or merely accelerated a decline already under way, is not clear. By the time Webster sketched the building in the early twentieth century, the east and west walls had already largely collapsed, though a lintelled doorway was still visible in the west wall at that point. Today the inner face of the north wall stands to roughly two metres in height, and the south wall survives along 8.8 metres from the south-east corner, enough to give a clear sense of the building's original footprint even as the superstructure continues its slow return to the ground.
