A single south wall still stands to its original height, smothered in ivy at either end and repointed along its central stretch sometime in the early 1980s. The other three walls have largely gone, reduced to low rises in the ground or, in the case of the west wall, to little more than a grass-covered mound tracing a straight line through the graveyard. What makes the ruin quietly compelling is partly what has already vanished. Before the east wall collapsed, a local historian named Power recorded in 1932 that it carried three arches side by side, each roughly six feet wide, with the central one pointed and slightly taller than its round-arched neighbours. Power found the arrangement puzzling, noting it resembled a chancel arch more than a straightforward end wall, though no trace of a chancel survived even then.

The church served the parish of Templeroan, a place mentioned as early as 1252, and was already described as being in ruins by 1615. A buttress-like projection at the south-east corner, noted by an earlier writer named Byrne in 1902, was tentatively identified as the remains of a sacristy, a small side chamber typically used for storing vestments and vessels, though the connection remains uncertain. Along the line of the vanished north wall, two burial vaults were later inserted into the site: one erected by a Garret Nagle in 1796, and another belonging to the Roberts family of Shanballymore. Their presence is a reminder that ruined churches in Ireland rarely became truly abandoned places; the ground around them continued to serve communities long after the roofs had gone.
