A church had stood here in the townland of Kilkiaran, roughly fifty metres northwest of the Sruhnasilloge river, but the surveyors recorded only "a little obsolete burying ground" with no remains of a structure. On their six-inch map they marked the outline of the building in dashed lines, a cartographic convention signalling that the walls were gone, and noted its approximate footprint: around twelve metres on its northeast-to-southwest axis, seven on the other. That dashed rectangle is now the most coherent image we have of the place.

The church appears under several shifting names in the Red Book of Ossory, a medieval ecclesiastical register for the diocese. Around 1350 it was listed as the "Capella de Lessentane," in 1351 as "Tainewyrghlan," and by around 1500 as the "Ecclesia de Lyssyntan." The historian Carrigan, writing in 1905, placed it within what he called the ancient territory of Lisnatawna, associated with the Dobbin family. He noted that by his time the churchyard was covered entirely in large rough stones, which he took to be the scattered remains of the demolished walls. The 1900 to 1901 Ordnance Survey revision still marked the site, now with a cross and within a smaller, unenclosed graveyard, as though the boundaries themselves had contracted over the decades.

What remains today is largely invisible at ground level. The graveyard is heavily overgrown with scrub and trees, and while stones lie scattered throughout, no standing structure survives. Within the graveyard there is a bullaun stone, a large rock with one or more rounded depressions worn or carved into its surface, often associated with early Christian and pre-Christian ritual practice, as well as a pillar stone. A stoup, a small vessel once used to hold holy water, has been recovered and is kept in a garden adjacent to the site. These objects, outlasting the walls that once surrounded them, are what give the place its only tangible continuity with the medieval chapel named, and renamed, and eventually forgotten in the ledgers of Ossory.
