This is the kind of layered strangeness that defines the ruined parish church at Dromkeen South, where the fabric of the building has been quietly cannibalised and reassembled across generations. Two medieval window sill-stones, for instance, were repurposed as quoins, the dressed corner-stones that give a wall its structural integrity, and now sit at the south-east angle of the church doing entirely different work from what was originally intended. The original doorway has left almost no trace, save for a single sandstone chamfered jamb, a door-frame stone with a bevelled edge, lying against the exterior of the south-west corner.

The church appears in records before 1250 under the name Dronchyn, and by the early fourteenth century it had passed through Anglo-Norman hands, associated with a family recorded variously as de Interberg and de Hynderberge. A legal dispute over the land was taken into the king's hands in 1323. By the late seventeenth century, the building had found a new purpose: from 1693, the De Burgh family used the interior as a private burial place. A plaque, now missing from its cut-stone surround in the south wall, recorded that the church was repaired in 1717 by the Reverend Rickard Burg, Lord Bishop of Ardagh, who noted it had served as his family's burial ground from time immemorial. Beneath the current concrete floor, local tradition holds that a burial vault remains intact. When the antiquarian T. J. Westropp documented the site in 1904 and 1905, the east gable and sections of the side walls were already the dominant features; a survey from 1840 described the same gable carrying a flat-headed rectangular window with a shallow segmental arch, a form that the later post-1700 replacement broadly echoes.

The ruins occupy elevated ground in Co. Limerick with open views in most directions, including across to Dromkeen House and Castle about 170 metres to the north-north-east. The medieval church stands immediately south of the north wall of the active graveyard, with the separate shell of a nineteenth-century Church of Ireland building a further 20 metres to the south, so there are effectively three distinct phases of religious architecture within a compact area. The east gable survives to near full height and is the most legible part of the structure, while the west wall stands only to about 0.8 metres. Tobereendoney Well, a named holy well, lies roughly half a mile from the church and may be worth locating for those with time to walk the surrounding area.
