Just north of the main burial ground lies a smaller enclosed area, roughly 12 metres east to west and 10.4 metres north to south, surrounded by stone walls that rise about a metre high. This modest enclosure creates an intimate space that feels separate from the everyday world, a characteristic feature of early Irish religious sites.

Within this walled sanctuary stands a small stone cross, marking the sacred nature of the space. Beside it sits a remarkable boulder, roughly half a metre in height and width but stretching a full metre in length, which local tradition identifies as a Mass Rock. These natural altars served Catholic communities during the Penal Laws when public worship was forbidden, transforming ordinary stones into clandestine places of devotion. The landowner confirms this boulder’s significance has been passed down through generations of local memory.

The site once boasted additional sacred features that have sadly been lost to time. A holy well, that essential element of Irish folk Christianity where pre-Christian water veneration merged with Catholic tradition, no longer survives. Also destroyed was a dallan or pillar stone dedicated to St. Adomnán, the seventh-century abbot of Iona who maintained strong connections to his native Donegal. These missing elements remind us that Templemoyle was once part of a richer sacred landscape, where natural features, carved stones, and communal memory combined to create a place of enduring spiritual significance.
