Not collapsed into a dramatic ruin, not reduced to a romantic scatter of dressed stone, but simply gone, absorbed into the graveyard that surrounds it. What had once been a place of worship dedicated to Saint Endeus, known in Irish as Teampull Eunna, had by that point left no visible trace above ground. The graveyard itself remains, its rectilinear outline still legible, but the rectangular church that once occupied its western corner has disappeared beneath it.

The building was already far gone by 1838, when Ordnance Survey officers visited and noted that it had been "so destroyed that no description of its original extent or form could be given." Only one side of the south doorway was then still standing. They remarked that it had been "very rudely built of large stones," suggesting a structure of considerable age and simple construction, typical of early Irish ecclesiastical buildings. By the 1920 edition of the same Ordnance Survey maps, its name had acquired a bracketed qualifier: Temple Eunna (in Ruins). In the early 1940s, surveyors could still make out the lower courses of those massive wall stones and faint traces of the door jamb. Then, within half a century, even that was gone.

The tradition attached to the site is worth pausing on. A local account, recorded in the 1940s, holds that the church was founded by a follower of St Patrick, who had been instructed by the saint to build wherever misfortune struck him on his journey. The man was travelling with a deer, the animal carrying his belongings, when the deer broke its leg crossing a stream. That, according to the story, was the sign. A broken leg, a flooded stream crossing, a pause in a landscape in Co. Mayo, and a church eventually rose from it. Roughly a hundred metres to the south-west, a holy well called Tober Eunna still exists, sharing the saint's name and quietly marking the same devotional geography that once made this unremarkable field corner something more.
