Local tradition connects this remote site with St. Duach, though little is known about the saint's actual connection to the island. The church itself was once a modest structure, measuring just 15 feet by 10 feet according to a description from 1858 in the Ulster Journal of Archaeology; a simple rectangular building with a single doorway on its southern side.

What makes this doorway particularly interesting is its unusual design: standing 5 feet high, it was 2 feet wide at the bottom but tapered inwards towards the top, creating a distinctive trapezoid shape typical of early Irish church architecture. This tapering design, often seen in medieval Irish buildings, helped distribute the weight of the stone walls more effectively whilst also creating a rather dramatic entrance to what was otherwise a humble place of worship.

The site hasn't been accessible for proper archaeological survey in recent decades, leaving much about its history shrouded in mystery. The church and its associated burial ground were already in ruins by the time they were recorded on the third edition of the Ordnance Survey 6-inch map, suggesting they had been abandoned for considerable time even then. As with many such sites scattered across Donegal's landscape, this small church represents centuries of local religious practice and community life, now reduced to weathered stones and folk memory.
