On a south-facing slope above the valley of the Owenboy River in County Cork, beside a farmhouse on the southern side of a road, lies what is recorded as an early church site, its presence detectable only through place-name evidence and a century-old fieldwork note. There are no visible remains whatsoever, no tumbled masonry, no earthwork, no trace of a boundary wall.

The site sits in the south-western corner of the townland of Kilnahone, the name itself a clue: "cill" is the Irish word for a church or early ecclesiastical enclosure, and its presence in a placename frequently signals a site of early Christian activity even when the ground itself has long since been cleared or built over. A researcher named O'Leary, writing in 1918, noted that the cill site "was found with much difficulty" on what was then White's farm, which gives some sense of how elusive the location was even then, more than a hundred years ago. That it required considerable effort to locate in 1918 says something about how thoroughly the physical evidence had already vanished by that point.
