No walls remain, no foundation courses, no dressed stone poking through the grass. The only surviving record of the building's shape comes from the first edition of the Ordnance Survey one-inch map, published in 1839, where a faint rectangular outline, roughly 20 metres east to west and 8 metres north to south, was labelled in gothic lettering as the site of a church, already a ruin or a memory even then.

The graveyard itself survives, a subrectangular enclosure measuring approximately 65 metres east to west and 40 metres north to south, defined by stone-clad earthen banks of the kind that frequently mark early ecclesiastical sites in Ireland, where the boundary between sacred and secular ground was given physical, lasting form. The western section is now overgrown and effectively inaccessible. What draws the eye on the map, beyond the vanished church itself, is the cluster of related sites nearby. St Margaret's Well lies around 480 metres to the north-west, and Rathumney Castle sits roughly 350 metres in the same direction. The proximity of the church to the castle raises the possibility that it functioned not as a parish church serving the surrounding community, but as a private or estate chapel, a building whose primary purpose was to serve the household and affairs of whoever held the castle rather than the wider population.

The relationship between castle, chapel, and holy well in this corner of Wexford suggests a small but coherent medieval landscape, each element close enough to the others to have formed part of a single social and spiritual world, even if the physical evidence above ground has largely been reclaimed by grass, scrub, and time.
