The walls are low and densely overgrown, the west end has collapsed entirely, and what remains of the structure would be easy to walk past without a second glance. Yet the outline is still legible: a building measuring roughly 14.3 metres east to west and 7.2 metres north to south, constructed from sandstone rubble set in mud mortar rather than lime, a technique common in early Irish ecclesiastical building that speaks to both the age and the modest means of the community that raised it.

Local tradition knows the place as Killeran, or sometimes The Kiles, names that suggest a dedication or a townland memory that the physical remains can no longer confirm. The outer facing of the south-east corner survives, along with a short stretch of the south wall, standing to little more than 75 centimetres at its highest. Towards the western end of that south wall, a gap roughly a metre wide is thought to be the remnant of a doorway, with an upright rectangular stone on its eastern side likely serving as a door jamb. By around 1840, according to the Ordnance Survey Field Book, the greater portion of the walls were still standing, which means the substantial collapse visible today has occurred within the last two centuries, a relatively swift deterioration for a structure that may have stood for many centuries before that.
