This modest stone structure, measuring just 8.15 metres long and 4.6 metres wide externally, is a National Monument under state guardianship. Though much of the western wall has collapsed over the centuries, the remaining walls still reach heights of up to two metres, offering visitors a glimpse into the religious life of this remote coastal community.

The church’s simple rectangular plan reveals several interesting architectural features despite its ruined state. A doorway, slightly off centre, pierces the southern wall, whilst the eastern wall contains both a splayed window opening and a peculiar small chamber at its base. This wall chamber, measuring just over a metre long and accessible through a tiny opening barely 30 centimetres wide, may have served as a secure storage space for religious items or perhaps as an anchorite cell. In the northeast corner, a drystone structure resembling an altar remains intact, and two ancient cross slabs rest atop the eastern wall, silent witnesses to centuries of worship.

Local tradition connects this mainland church with a similarly named structure on Rathlin O’Birne island, visible some two kilometres offshore to the west. This connection hints at a broader network of early Christian sites along this stretch of Donegal’s Atlantic coast, where isolated communities maintained their faith despite, or perhaps because of, their remoteness. The church’s position, overlooking Malin Bay with its dramatic coastal scenery, would have provided both spiritual solace and practical advantage, allowing the community to monitor maritime traffic whilst maintaining their devotions.
