This one in Bannow, County Wexford, offers none of that. What survives is a shallow depression in the ground, roughly half a metre across and thirty centimetres deep, fed by land drainage pipes, sitting quietly about two metres south of an old field bank. It is the kind of thing a person could walk past without registering at all.

And yet cartographers thought it worth marking twice. The Ordnance Survey six-inch maps of 1839 and 1925 both record it, on each occasion in gothic lettering, the typographic convention reserved for antiquities and sites of particular character. John O'Donovan, the scholar and Irish-language specialist who travelled the country around 1840 gathering place-name evidence for the first Ordnance Survey, noted it as a holy well, though he recorded no further detail, which suggests even then there was little visible tradition attached to it. Holy wells, as a category, were typically venerated springs associated with a saint or with healing, often visited on a particular patron day and marked by some form of ritual practice. Whether any of that applied here, the historical record does not say.

The site lies on broadly level ground with slightly higher land rising to the east, a modest topography that gives no obvious clue as to why this particular spot was considered sacred. What remains is essentially a gap in the evidence: a name preserved through two centuries of mapping, a passing mention by one of Ireland's most diligent nineteenth-century scholars, and a small wet hollow in a County Wexford field.
