By 2019, three decades after a first recorded inspection, its interior had become entirely inaccessible, closed off by dense overgrowth and accumulated field-clearance debris. The building measures roughly 15.5 metres east to west and just 6 metres north to south, its walls built from uncoursed mortared blocks of roughly cut granite. Both gables still stand, the eastern one reaching about 3 metres in height, and the lower courses of the southern wall survive even where the upper sections have collapsed. No decorative or architectural features remain visible. A small stone structure of uncertain purpose sits near the south-east corner, its function unrecorded.

The church was known in Ordnance Survey correspondence as 'Barna old chapel', a name used specifically to distinguish it from a later Roman Catholic chapel that once stood roughly 90 metres to its west-south-west. That distinction matters: it points to the older building as a probable pre-emancipation Catholic church, meaning it would have been used during the Penal era, the period before the Catholic Relief Act of 1829, when Catholic worship was technically restricted and congregations typically gathered in modest, unadorned structures far removed from the elaborately fitted-out churches built afterwards. The name An Cnocán Carrach, meaning something close to 'the rough little hill', suits the setting well. Associated with the ruins is a graveyard, and about 40 metres to the east lies a holy well, the kind of freshwater spring long treated as sacred in Irish tradition and often found in close company with early ecclesiastical sites.
