The enclosure, defined by an earthen bank, contains the foundations of three or four rectangular house sites, a possible souterrain (an underground passage or storage chamber, typically associated with early medieval settlement), and the roofless shell of a church known variously as Templemartin, Teampall Mártain, or An Teampall Liath. What makes the site stranger still is that children were interred here until the early part of the twentieth century, yet no graves or grave markers are now visible.

The church itself tells the story of at least two distinct phases of building. The original structure is a pre-thirteenth century foundation; it was extended eastwards, probably during the fifteenth or sixteenth century, though the junction between the two phases is difficult to read now because the stonework at that point has deteriorated badly. Two roughly opposed breaks in the north and south walls, about six metres from the west gable, may mark where the later extension met the earlier fabric and failed, the newer masonry too poorly bonded to hold. The western portion of the building survives best, with the north and south walls standing to around 2.3 metres. The original doorway is still largely intact in the west gable: its jambs are formed of neatly squared blocks with inclining ingoings, the whole framed by a sunken architrave with a projecting half-round moulding on the reveals, and the lintel, a substantial single stone, still carries a broken pivot hole that once took the door's hanging pin. A metal or wooden gudgeon seated in an angled groove in the wall secured the door from below. The later extension was clearly the work of less careful hands; the east gable and the return of the south wall show wider joints and heavier use of pinning stones to fill gaps. A single-light ogee window from this later phase has partly collapsed, its head found wedged under the lintel of the doorway, and two chamfered block jambs now lie fallen near the east wall, which stands only around a metre high.
