This church, known locally as Teampall an Phoill, is one of the seven that make up Na Seacht dTeampaill, the Seven Churches, a site that draws visitors more often for its monastic atmosphere than for any single building within it. What singles out Teampall an Phoill is its compactness and the quiet precision of its surviving stonework. At less than eight metres long and just over four metres wide, it is a modest structure, yet it retains details that reward a close look.

The church is oriented east to west, as was standard in medieval ecclesiastical architecture, with the altar end facing Jerusalem. Its pointed-arch doorway follows a Gothic tradition that became common in Irish church building from the twelfth century onwards, while the trefoil-headed window in the east gable, a single narrow light with a three-lobed head carved into the stone, belongs to a decorative vocabulary found across later medieval Irish religious buildings. A ruined window survives in the north wall, though in poorer condition. Scholars including T. J. Westropp, who wrote about the site in 1895, and John Waddell, whose work on the churches appeared in 1973, have each noted these features, suggesting the building attracted attention well before any formal conservation effort was undertaken.
