There is no doorway. There are no grave markers. The south wall has vanished entirely, and the ruins that do survive, portions of the north and east walls, are in poor condition. Only the west gable still carries any real presence, rising to nearly five metres and containing a window that has been blocked up at some point, its original purpose sealed off as completely as the building's history.

The church itself is modest in scale, measuring roughly 11.5 metres east to west and 5.7 metres north to south, and was built from roughly coursed limestone, a common enough material in this part of Connacht where the stone occurs naturally in abundance. Beyond its dimensions and its construction method, the building offers little to anchor it to a particular period or community. The absence of associated burial ground is unusual; rural churches in Ireland were almost always surrounded by or adjacent to graveyards, which often continued in use long after the building itself had fallen into ruin. That there is no trace of grave markers here makes Rocksborough a quiet outlier.

The ruins sit in ordinary farmland, without signposting or formal access, and the fabric of the walls is fragile enough that the site rewards careful attention rather than close inspection. The blocked window in the west gable is the one element that repays a long look, hinting at alterations or perhaps a later phase of use that went unrecorded.
