The building is thoroughly ivy-clad now, but the stonework beneath, roughly coursed ashlar, still holds the shape of the original rectangle, measuring around 7.7 metres north to south and 15.6 metres east to west. The north and south walls have been worn down to little more than low courses, offering almost nothing in the way of detail. The interest lies in the two gables, which have fared considerably better.

The east gable retains a large Romanesque window, a round-arched form characteristic of pre-Gothic ecclesiastical building in Ireland, broadly associated with the twelfth and early thirteenth centuries. Its survival in the east wall is fitting, given that early Irish churches were typically oriented so that morning light would fall through the east end and onto the altar. The west gable holds the entrance doorway, standing at 1.8 metres in height, with a splayed internal reveal, meaning the opening widens as it passes through the wall thickness, a practical device that draws more light into the interior. Together, these two features suggest a building of some ambition for its setting, even if what remains above the foundations is fragmentary.
