These dressed stones and mullions once formed part of the church’s east window, a feature that would have been one of the building’s most impressive elements. When the antiquarian Doherty visited in 1891, he noted that the window had been constructed from cut stone, and by then, many of its component pieces lay strewn about the churchyard.

The fragments represent skilled craftsmanship from a time when such decorative stonework was a mark of a church’s importance to its community. Stone mullions, which would have divided the window into vertical sections, required precise cutting and shaping to create the Gothic or Tudor style typical of 17th-century Irish ecclesiastical architecture. These architectural elements would have supported stained glass or plain glazing whilst creating an elegant geometric pattern that drew the eye upward.

Despite their historical significance, these stone fragments had vanished by the time the Donegal Survey team arrived to document the site in 1983. Whether they were removed, buried, or repurposed elsewhere remains unknown, leaving only written records of their existence. The disappearance of these architectural pieces mirrors the fate of countless similar fragments across Ireland, where centuries of weather, neglect, and human intervention have scattered or destroyed the physical evidence of the country’s built heritage.
