The church that once stood here has effectively returned to the earth, invisible at ground level, with only the historical record to confirm that anything was ever here at all. Even the name on the Ordnance Survey map turns out to be wrong.

When Ordnance Survey officers recorded the site in 1839, they found a doorless, windowless western gable and a foundation traceable to roughly 52 feet in length and 18 feet in breadth, just under 16 metres by 5.5 metres. The local people called it Árt an Fhíona, a name the OS Letters faithfully noted. The historian Carrigan, writing in 1905, was more exacting: he identified the church's true name as Teampull Bhuirghiasa Mhóir, and dismissed the Ordnance Survey's "Ardaneena Church" as, in his words, absolutely without foundation. By Carrigan's time, the structure had already been heavily robbed out; both gables and fragments of the side walls had survived until less than eighty years before he wrote, but had since been taken away. What remained was a partial west gable and a curious small square structure attached to its outside, stone-roofed, loopholed in the sides, with its entrance leading from the interior of the church. Carrigan interpreted this as a kind of secure locker or safe for vestments and altar vessels, a feature sometimes seen in medieval Irish churches where portable sacred objects needed protection. Healy, who visited slightly earlier, in the 1870s, noted only a small portion of the gable still standing and observed an opening that appeared to have led to a special staircase. No graveyard was ever identified at the site. A similar hillock roughly 160 metres to the south-east is now occupied by Wilton House, giving a sense of the modest, hummocky landscape that the church once shared with its surroundings.
