A bullaun stone is not usually something you expect to find at the bottom of a lane, yet that is precisely how this quietly anomalous site in County Waterford gave up one of its oldest secrets. Bullaun stones are boulders or slabs carved with one or more rounded depressions, and they are closely associated with early Christian sites across Ireland, their original function still debated but their presence almost always a signal that something significant once stood nearby. At this old graveyard in the Dawn river valley, the bullaun came to light when the original ecclesiastical enclosure, the boundary that would have defined and protected a monastic or church precinct, was cut through to create a north-south lane.

The site sits on a natural shelf on the northern side of the valley, with the Dawn river running roughly east-west about a hundred metres to the south. When John O'Donovan visited the area around 1840 as part of the Ordnance Survey, he recorded a local tradition identifying this as the church site of St Dimóg, also known as St Dima, an obscure early Irish saint whose name is preserved in the placename Kilmoyemoge itself. The prefix "kil" derives from the Irish "cill", meaning a church or monastic cell, and its presence in the townland name suggests the memory of that foundation ran deep even as the physical remains dwindled. The site appears on the 1840 edition of the six-inch Ordnance Survey map simply as "Old Grave Yard", and Rev. Patrick Power, writing in the mid-twentieth century on the placenames of the Decies, the ancient territory covering much of County Waterford, described the ecclesiastical enclosure in some detail. By that point the enclosure had already been broken to make the lane, and the displaced bullaun stone was the most tangible trace of what had once been a defined and bounded sacred space.
