On a south-facing slope in County Waterford, on a low knoll at a place called Bawnfune, there is a site that local tradition has long called a cill, the Irish word for a church or small ecclesiastical enclosure. No walls survive above ground, no carved stonework, no obvious outline. When the field is ploughed, an oval spread of stones, roughly two metres wide and enclosing an interior space of about 37 metres by 26 metres, is all that betrays what was once here. There is no evidence of burial, which sets it apart from the classic early medieval graveyard enclosure and leaves the question of its original function genuinely open.

The site has a curious cartographic history. On the 1840 edition of the Ordnance Survey six-inch map, it was recorded as a sub-triangular embanked enclosure, with its apex pointing north, measuring roughly 60 metres north to south and 50 metres east to west. By the time the 1927 edition was produced, the same site had been mapped as a sub-rectangular enclosure, its dimensions recorded differently again. Whether the shape of the earthwork itself changed over those intervening decades through agricultural erosion and ploughing, or whether the difference reflects the judgement of individual surveyors working from ground level, is unclear. Raftery and Haworth noted the site in a 1944 preliminary report on places of archaeological interest in County Waterford, one of the earlier systematic attempts to catalogue such remains across the county, which gives some sense of how long this modest enclosure has been quietly accumulating scholarly attention without ever quite resolving into a definitive answer about what it was.
