The site centres around a modern rectangular graveyard measuring 22 metres north to south and 20.5 metres east to west, but it’s the older elements that truly capture the imagination. Just north of the graveyard, visitors will find a sub-rectangular enclosure spanning 12 metres by 10.4 metres, surrounded by stone walls that still stand a metre high despite their age. This levelled interior space, with what appears to be an entrance on its southern side, likely served as a sacred area for early Christian gatherings.

The most intriguing features lie to the east of this enclosure. Here stands a distinctive D-shaped mound of earth and stone, rising 1.5 metres high and stretching 8 metres across, with its flat edge facing eastward. This unusual earthwork has a small circular stone foundation, just 2.2 metres in diameter, built directly against its western side, suggesting these structures were designed to work together in some religious or ceremonial capacity. A small stone cross marks the interior of the complex, serving as a tangible link to the site’s spiritual past.

Though some elements have been lost to time, local tradition preserves their memory. The site once boasted a holy well and a dallan, a type of pillar stone dedicated to St. Adomnán, an important 7th-century abbot of Iona with strong connections to Donegal. While these features no longer survive, their documented existence adds another layer to Templemoyle’s rich ecclesiastical heritage. The complex represents a typical Irish early Christian site, where natural features, constructed monuments, and sacred dedications combined to create spaces of worship and contemplation that served local communities for generations.
