The absence of any window openings is quietly striking: a rectangular structure of uncoursed rubble, roughly sixteen and a half metres long and eight metres wide, with a single doorway set into the west end of the north wall, admitting no light from the outside world except through that one entrance. The walls survive to an average height of around a metre and a quarter, and their substantial width of 1.2 metres suggests a building that was made to endure.

The church occupies the south-east corner of an enclosure measuring approximately sixty-five metres north to south and fifty metres east to west. This kind of oval or curvilinear enclosure is a recurring feature of early Irish ecclesiastical sites, where the boundary itself, rather than any single building, often defines the sacred space. Here, the southern edge of the enclosure is marked by an earthen bank with external drystone facing and a shallow outer fosse, a term for a ditch or trench dug as part of a boundary or defensive arrangement. The eastern and north-eastern sides are indicated by a slight scarp, a low natural or man-made slope in the ground. Within this enclosure, the southerly area was put to use for burials during the eighteenth and early nineteenth century, layering a later, more familiar kind of commemoration over a much older arrangement of space.
