What makes it unusual is not its size, which is modest at roughly 2.7 metres by 2.2 metres, but the detail at its northeast corner: a limestone block placed on top of the enclosing wall holds a natural solution hollow, a shallow depression formed over millennia by slightly acidic water dissolving the rock, and that hollow contains a scatter of coins left as votive offerings. The well itself was dry and grassed over when visited, yet the coins suggest the place remains, in some quiet way, in use.

According to local tradition, as recorded by Pat McNamara of Dereen West, Fanore, this is a holy well. Holy wells in Ireland are typically springs or water sources associated with a saint or with older pre-Christian belief, and they have long attracted patterns of devotion: prayers, ritual circuits, and the leaving of small offerings. The structure here is built with some care. The enclosure walls, constructed from four to five courses of large limestone slabs and stones laid without mortar in the drystone tradition, stand around 0.65 metres high and run to a width of 0.4 to 0.5 metres. The east wall is built directly against a rising scarp of bedrock, making use of the natural landscape as part of the architecture. A narrow entrance gap of roughly 0.25 to 0.3 metres opens at the south end of the west wall, wide enough to pass through only with deliberate effort, the kind of threshold that marks a transition rather than simply a passage.

The plateau setting places this well within a broader archaeological landscape. The surrounding field system is extensive, pointing to a long history of human activity on this upland terrain. The Burren, of which this area forms a part, is karst country, meaning the underlying carboniferous limestone has been shaped by water into a distinctive surface of pavements, grikes, and natural hollows. That the coins rest in a solution hollow rather than a purpose-built vessel is a small but telling detail; the geology itself has been incorporated into the devotional life of the place.
