The site shows no signs of burial, which sets it apart from the typical pattern of rural Irish ecclesiastical remains, where a church and its graveyard tend to go hand in hand across the centuries. That absence points towards a particular function: the building was likely a chapel-of-ease, a secondary place of worship built to serve parishioners who lived too far from the main parish church to attend it comfortably, without itself holding the full rights of a parish church, including burial.

A Catholic church listed around 1680 by a writer named Synnott, and later cited by the historian Hore in 1862 and again in 1921, identifies a chapel in this area dedicated to St George. The foundations that survive measure roughly nine metres east to west and four metres north to south, a modest footprint even by the standards of rural medieval chapels. They sit within a grass-covered, subrectangular area approximately 29 metres by 12 metres, partly edged by a straight road bank to the west, a curved field bank to the north that doubles as a townland boundary between Rathmore and Ballydungan, and a low earthen bank to the south. If the identification is correct, the building served a patch of level Wexford farmland positioned between two older parish churches: Kilscoran, around 1.6 kilometres to the north, and the church of St Iberius, roughly 1.3 kilometres to the south. Placed almost exactly between them, this small chapel-of-ease would have offered a practical middle point for a scattered rural congregation.
