Built during the medieval period, this parish church underwent significant alterations around 1622 when it was converted for Protestant worship, reflecting the broader religious upheavals of the time. The church continued to serve its congregation until 1792, when a new place of worship was constructed at nearby Manorcunningham, leaving the old building to gradually surrender to nature.

The church’s surviving structure, measuring approximately 6.45 by 17.65 metres internally, reveals a fascinating architectural timeline through its rubble walls and ashlar quoins. The most striking feature is the complete eastern gable with its round-headed, three-light window; an insertion likely dating to the 17th-century renovations, featuring simple switchline heads and splayed openings constructed from horizontally laid flat stones. The northern wall preserves evidence of four windows, though only the central one of the three easternmost windows retains its original splayed openings and segmental rear arch, whilst the westernmost was blocked up after its head and rear arch were removed.

Despite the collapse of the southwest corner and much of the southern wall’s interior face, careful archaeological investigation has revealed numerous medieval details. The main doorway, positioned in the north wall near the western gable, features eastern jambs composed of three chamfered blocks with an interior rebate for the door, all displaying the characteristic punch dressing typical of 15th-century craftsmanship. Intriguingly, several medieval window fragments from the church have found new life built into the gate piers of the surrounding graveyard, whilst another fragment was incorporated into the western gable’s exterior fabric, ensuring that even in decay, pieces of Raymoghy’s medieval heritage remain visible to observant visitors.
