A bullaun is a rounded boulder with one or more cup-shaped hollows worn or carved into it, objects associated in Ireland with early ecclesiastical sites and, often, with folk cures or ritual use. Here it rests not in its original context but fixed onto masonry that is itself largely a 20th-century reconstruction, possibly built over the original foundations. The west wall has vanished entirely. The sod-covered interior holds several low, uninscribed stone grave markers, irregular in shape and anonymous. A possible spud stone, a flat rectangular block with a shallow circular depression, lies at the east end; such stones are thought to have served as pivot sockets for gates or doors.

When a member of the Royal Society of Antiquarians of Ireland visited in the early 1870s, the church was in considerably better condition. His account, published in the Society's journal for 1870 to 1871, described most of the eastern gable still standing at roughly 7.3 metres, along with portions of the western gable and south wall. He measured the building at about 12.8 metres in length by 6.7 metres in width, with walls 0.75 metres thick. What caught his attention most was a narrow window in the east wall, its semicircular head cut from a single stone, its jambs fitted with what he called "the utmost exactness". The proportions and style placed it, in his assessment, to around the middle of the 14th century. The 1838 Ordnance Survey six-inch map already marked the building as a church in ruins; by the 1929 edition, it was named Teampull na Macaire and only the east and west walls were indicated. By the 1930s, local memory held that the gables still stood to about 7 metres. By the time Lavelle documented the site in the early 1990s, no architectural features remained at all, and what defines the church outline today is a low concrete-capped wall of modern construction.
