That ambiguity seems fitting. What remains of this rectangular church, oriented east to west as was customary, amounts to the eastern gable and short stretches of the north and south side-walls, the whole structure measuring roughly ten and a half metres in length and six metres wide externally. It is modest even as ruins go, and easy to pass without pausing.

The single surviving architectural feature is a pointed arch window set into the eastern gable, partially blocked at some point, though whether through deliberate closure or gradual collapse is unclear. The pointed arch, a form associated with Gothic influence and widely used in Irish ecclesiastical buildings across several centuries, gives little away about precise dating on its own. The building is thought to have been a Roman Catholic chapel, constructed sometime during the eighteenth or nineteenth century, a period when Catholic communities across Ireland were slowly moving from informal or outdoor worship into more permanent, if often modest, purpose-built structures. Monivea itself was an estate village, meaning it was planned and developed by a landlord family rather than growing organically, which adds a particular social context to the question of who built this chapel and under what circumstances.

The ruin sits close to the street, which means it is visible without any particular effort of exploration. The partially blocked window in the east gable is the detail worth looking for, the one remaining trace of the building's original form above the level of bare masonry.
