What remains is a name on an old map, a ghostly annotation reading "Site of", and the knowledge that something genuinely old once stood here.

The church was known as Cill O'Mainné, a name recorded in the Ordnance Survey Letters compiled by John O'Donovan in the nineteenth century and later published by Michael O'Flanagan in 1927. O'Donovan noted that by his time nothing more than the foundations survived, and he considered it more ancient than the nearby church at Ballynakill, itself no newcomer to the landscape. The site sits within an early ecclesiastical enclosure, the kind of roughly circular or oval boundary, often detectable as a raised bank or curving field edge, that typically marks the original precinct of an early medieval Irish religious settlement. Cill O'Mainné almost certainly predates the Norman reorganisation of the Irish church, placing its origins somewhere in the early medieval period. By the time the Ordnance Survey produced its first edition six-inch map in the nineteenth century, the church had already disappeared so completely that the surveyors did not mark it at all. It was only on the third edition, published in 1930, that a "Site of" notation appeared, acknowledging the tradition of its location. Today, neither the church nor the associated graveyard, also named on that later map, leaves any visible trace on the surface.
