Marked on Ordnance Survey six-inch maps from both 1839 and 1925, identified each time in gothic lettering as St. Davin's Well, it occupies a small valley where a stream meanders north-east through deciduous woodland. By the time anyone went looking in recent decades, the well itself had become difficult to identify, possibly reduced to a small pool on the southern bank of the stream. The parish church of Kildavin sits roughly 150 metres to the south-east, close enough to suggest the two sites once formed part of a shared local geography of devotion.

The saint in question is St. Damhán of Feamore in Old Leighlin, County Carlow, recorded as a brother of St. Abán of Adamstown. A pattern, the traditional Irish gathering of prayer and community celebration held at a holy well on a saint's feast day, took place here on the first of August. That date carries some weight: the first of August is Lughnasa, an ancient harvest festival with pre-Christian roots, and scholars have noted the overlap between Lughnasa and many patterns held on or around that date across Ireland. There is, however, no other evidence connecting this particular well to Lughnasa observance, and the association remains speculative. John O'Donovan, writing around 1840, recorded the pattern as already discontinued for some twenty years, meaning the last gatherings at the well likely took place around 1820. By the time the Victorian map-makers named it in gothic script, it was already a place being remembered rather than actively used.
