The blocks were not discarded; they were reused, as was common practice across rural Ireland when an abandoned ecclesiastical building became, in practical terms, a quarry. What remains in the field itself is only a fragment of the western wall, rising from pasture with no wider structure to contextualise it.

By the time the Ordnance Survey produced its six-inch map in 1842, the site was recorded as including both a church and a graveyard. That graveyard has since left no visible trace on the ground, which is itself a striking kind of disappearance. Burial grounds tend to persist in the landscape even when every other feature has been swallowed by grass or ploughing, often because communities maintain some quiet awareness of where the dead lie. At Cloonderreen, that awareness, if it ever lingered, has not preserved anything that can now be seen. The dressed stone in the nearby farmyard is the most legible thing left of the whole complex, the building's craft surviving in reuse long after its walls came down.
