The walls stood at around ten feet high and measured roughly forty feet by twenty, a compact footprint that sits at the modest end of what one might expect from a friary. That tentativeness in the historical record has never fully been resolved, and the site continues to carry its ambiguity quietly.

Known locally through the name Castletown church, the ruins form the northern boundary of a small rectangular graveyard at Carrig Beg, situated in open grassland close to the Cahernahallia River and within roughly 215 metres of Coonagh Castle to the west. The graveyard itself measures approximately 25 metres north to south and 32 metres east to west, enclosed by a post and wire fence with a stone wall and entrance gate at the southern end of a short stretch of east wall. Inside the western end of the church stands a nineteenth-century inscribed memorial to the O'Brien family of Coona, providing one of the few firm human anchors in an otherwise underdocumented place. To the south of the church, a cluster of low uninscribed stones marks out burial plots, though the Ordnance Survey noted as early as 1840 that only a few interments were taking place at that time. Curiously, there are no stones or grave markers of any kind in the area to the north and west of the church.

The site sits in grassland, so the approach is likely to be damp underfoot in wetter months. The entrance gate is at the southern end of the east wall, which is the clearest way in. Once inside, the uninscribed stones to the south of the ruin repay a slow look; their plainness contrasts with the O'Brien memorial inside the church walls, which is legible and worth seeking out. The proximity of Coonagh Castle to the west means the wider landscape holds further archaeological interest for anyone willing to cover a few hundred metres of ground.
