The site centres around a modern rectangular graveyard measuring 22 metres north to south and 20.5 metres east to west. Just north of this, visitors will find a smaller sub-rectangular enclosure, approximately 12 metres by 10.4 metres, surrounded by a stone wall standing one metre high with what appears to be an entrance on its southern side.

The complex reveals several intriguing archaeological features that hint at its long religious history. To the east of the walled enclosure sits a distinctive D-shaped mound made of earth and stone, rising 1.5 metres high and spanning 8 metres in diameter, with its flat edge facing eastward. Against the western side of this mound, archaeologists have identified a small circular stone foundation, just 2.2 metres across, whilst a simple stone cross stands within the interior space. Though no longer visible today, historical records tell us that a holy well once existed nearby, along with a dallan, or pillar stone, that was dedicated to St. Adomnán, suggesting this site held particular importance in early Irish Christianity.

This archaeological description comes from the comprehensive ‘Archaeological Survey of County Donegal’, compiled by Brian Lacey and his team in 1983, which catalogued field antiquities throughout the county from the Mesolithic Period through to the 17th century. The survey provides invaluable documentation of sites like Templemoyle, preserving knowledge of Ireland’s rich archaeological heritage even where physical remains have been lost or damaged over time.
