What survives of this rectangular church near Dunsandle amounts to three fragments: the north gable, the west side-wall, and a short return of the east side-wall at the north-east corner measuring only about one and a half metres before it stops. The south gable has vanished so completely that there is no visible trace of it at ground level. The footprint of the original structure was roughly fifteen metres north to south and seven and a half metres east to west, making it a modest but not tiny building, and its walls were built in the manner common across medieval Connacht, randomly coursed mortared limestone blocks laid without any pretence of precision but capable, evidently, of standing for centuries.

The church sits some fifty metres to the north of Dunsandle Castle, which suggests the two buildings once formed part of the same estate landscape, a private or manorial chapel positioned within easy reach of the house it served. Inside the ruins, the outline of an internal dividing wall is still evident, a detail that hints at some functional subdivision of the interior, perhaps separating a nave from a chancel, though the surviving fabric alone cannot confirm this. The only architectural feature that has come through intact is a plain rectangular-headed window placed at the apex of the north gable. It is an unadorned opening, without moulding or ornament, and its survival at the highest remaining point of the wall is partly a matter of luck and partly a consequence of the north gable being the most complete section left standing.

Visitors approaching from the direction of Dunsandle Castle will find the ruins a short walk to the north. The low remaining walls and the absence of the south gable mean the structure reads more as a ground plan than as a building, so arriving with some sense of its original dimensions helps to make sense of what the eye is actually seeing. The window in the north gable, plain as it is, remains the most legible element of the whole site.
