It does not break the surface. It left no trace in archaeological testing carried out in the vicinity. Its only documentary footprint is a single cartographic entry, rendered in the gothic lettering that Ordnance Survey mapmakers reserved for ancient and ecclesiastical features, on the 1940 edition of the six-inch map, where it is named St. David's Well. By that point it had already been closed up. Today it is not regarded locally as a holy well at all, even if people are aware something once stood there.

The dedication to St. David is itself a small curiosity. David was a sixth-century bishop of Menevia, in south Wales, celebrated for his preaching against the Pelagian heresy, a theological controversy concerning free will and grace that continued to trouble the early Church long after its official condemnation. He presided over church councils at Brefi and Caerleon and is the patron saint of Wales, with a feast day on 1 March. His veneration in Ireland was not unusual; early medieval Christianity moved freely across the Irish Sea, and dedications to Welsh and Breton saints appear in unexpected corners of the Irish landscape. Whether a pattern, the traditional gathering held at holy wells often on a saint's feast day, was ever observed here is not recorded. The well sits approximately twenty-five metres south-east of the site of Bridgetown Castle, in a low-lying stretch of ground with the Bridgetown river running roughly east to west some 130 metres to the north, and the two sites together suggest a landscape that was, at some point, considerably more active than its current quiet pasture would imply.
