The structure is modest by any measure, roughly six metres east to west and five and a half metres north to south, with walls that still stand to an average height of one and a half metres. A lintelled doorway, in which a single flat stone spans the opening rather than an arch, survives in the west wall, while the east wall has been reduced to a sod-covered foundation. What remains is thought to be a small oratory, the kind of intimate, single-cell prayer building that was a common feature of early Irish monastic and ecclesiastical sites.

The slightly unconventional axis, running ESE to WNW rather than the more standard east-west alignment found in later medieval churches, is one of the small details that marks this out as genuinely early in character. Early Irish ecclesiastical enclosures were typically circular or oval boundaries, often defined by a bank and ditch, within which oratories, burial grounds, and ancillary structures were arranged. The positioning of this building in the north-western quadrant of such an enclosure follows a pattern seen at other early Christian sites across Ireland, where different zones within the enclosure carried different functions or levels of significance. The dry-stone construction, with no mortar binding the walls, points to a building tradition associated with the earliest phases of Irish Christianity, before the introduction of more elaborate Romanesque stonework in the twelfth century.
