Observers noted in the 1920s that it provided a copious supply of good water but did not appear to possess any especial sanctity at the time. For a site on one of the most mythologically charged hills in Ireland, long regarded as the ceremonial and cosmological centre of the country, that is a curious kind of understatement. The well had been put to work supplying Lunestown House, which may go some way towards explaining its diminished spiritual reputation.

The well was already a thing of tradition rather than active practice when John O'Donovan recorded it during the 1837 Ordnance Survey Letters, noting that local memory held there had been a well on the hill called St Patrick's. It appeared as a spring on the 1838 Ordnance Survey map, with a stream flowing south-west, but the name itself was never printed on any Ordnance Survey edition. Uisneach is associated with a cluster of springs and bodies of water that may have carried ritual significance long before any Christian dedication, and this well is considered one of that broader grouping. Whether the Patrick association was a medieval imposition onto an older site, as is common with holy wells across Ireland, the notes do not say, but the pattern is a familiar one.

The well today is enclosed within a modern rectangular wall with iron railings and set on a stone pavement. Immediately to its north-west sits a squat, upright stone that has drawn archaeological attention. It is roughly D-shaped in cross-section, smooth and vertical on its broad southern face, with a rounded top, and appears to be made from locally derived limestone. It is oriented east to west. Whether it is a prehistoric marker, a later boundary stone, or something else entirely has not been determined, but its presence beside the well adds another layer of quiet ambiguity to a spot that has never quite settled into a single meaning.
