The surveyors recorded it plainly as "R.C. Chapel (in ruins)", which means it had fallen out of use before the Great Famine, before Catholic Emancipation had fully reshaped the landscape of Irish worship, possibly long before either. That the building was already gone while the country around it was still being formally measured and named gives it a particular quality of absence.

What survives roadside is a small rectangular shell, measuring roughly 6.9 metres along its longer axis and 4 metres across internally, with walls still standing to about 1.8 metres. The masonry is relatively slight, just under 60 centimetres thick, consistent with a modest rural chapel of the penal or immediately post-penal era, when Catholic congregations across Ireland built plain, unadorned structures with few architectural pretensions. The layout follows a straightforward logic: the entrance was through the south-west wall, and the altar sat at the north-east end, where two narrow windows with flat lintelled heads would have drawn in whatever light the orientation allowed. Lintelled windows, in which a single horizontal stone spans the opening rather than an arch, were common in vernacular religious buildings of this period, simple to construct and requiring no specialist stonework.
