That absence of windows is quietly striking. Early Irish churches were sometimes built with very limited fenestration, emphasising enclosure and interiority over light, but here there is no trace of any opening at all beyond a single doorway placed at the western end of the north wall, an unusual position that departs from the more typical west-facing entrance.

The church measures roughly 16.7 metres east to west and 8 metres north to south, with walls built of uncoursed rubble around 1.2 metres thick. It sits at the south-eastern corner of an oval enclosure, a shape strongly associated with early medieval ecclesiastical sites in Ireland, where the curving boundary, known as a cashel or vallum depending on its construction, demarcated sacred ground from the surrounding landscape. Here the enclosure runs approximately 65 metres north to south and 50 metres east to west. Its southern boundary is formed by an earthen bank with external drystone facing and a shallow outer fosse, a term for a defensive or boundary ditch, while the eastern and north-eastern sides survive only as a slight scarp in the ground. The southern portion of this enclosure was put to use as a burial ground during the eighteenth and early nineteenth century, suggesting that local communities retained some attachment to the site long after the church itself had fallen out of regular use.
