The walls lean outward slightly, worn down to their foundations in places, with two windows and what appears to be a blocked doorway still discernible in the south wall, and a window and a small alcove surviving in the north. The church runs east to west, as was conventional for medieval Christian buildings, and measured roughly 26.5 metres long by 8.5 metres wide, though you would struggle to read that scale from what survives today.

The ruin sits within the landscape of the medieval borough of Claregalway, a planned urban settlement of the kind established across Ireland during the Anglo-Norman period. The friary that most visitors to Claregalway come to see lies about 150 metres to the northwest; this church, by contrast, is thought to have served the borough's lay parish, making it a distinct and separate institution from the Franciscan community nearby. The two walls that remain are described as battered externally, meaning they slope slightly inward toward the base, a technique used to add structural stability. That the building has been reduced to this state suggests centuries of neglect and likely stone-robbing, a common fate for medieval parish churches that fell out of use after their congregations dispersed or their settlements declined.
