The curve of the road itself may preserve the memory of an ancient enclosure that once marked this sacred ground. Inside the graveyard stand the remnants of a church that served the local parish from at least 1622, when records show it was ‘well and sufficiently repaired’, until 1820 when a new church was built to replace it.

The entrance to the graveyard is flanked by two remarkable stones that hint at the site’s deeper past. On the south side, a small slab measuring 41cm by 32cm bears a carved wheeled cross, strikingly similar to another stone found near Clonca. Opposite this, built into the wall, sits a larger stone measuring 66cm by 50cm with a circular hole bored through it, 14.5cm in diameter. These holed stones, found at various early Christian sites across Ireland, may have served ritual purposes, though their exact function remains a subject of scholarly debate.

The site’s religious significance extends beyond the graveyard walls. Nestled in a valley between Collan Hill and Carrick Hill, Fahan’s spiritual landscape includes a holy well dedicated to St. Mura, located about 350 metres northwest of the churchyard near the lough shore. This combination of church, carved crosses, mysterious holed stone, and holy well creates a rich tapestry of devotion that has drawn pilgrims and parishioners to this corner of Donegal for centuries.
