That typographic distinction matters, because the well itself is gone. What the maps recorded, and what the landscape no longer shows, is Lady Well, a holy well almost certainly dedicated to the Blessed Virgin Mary.

Holy wells dedicated to Mary are common across Ireland, forming part of a devotional geography that pre-dates the Reformation and in many cases absorbed older, pre-Christian associations with sacred water sources. This particular well sat just south-west of its stream and immediately south of what is now the R374, the road running between Fethard-on-Sea and Slade on the southern tip of the Hook. The fact that it was still considered worth naming and marking on the 1925 edition of the six-inch map suggests it retained some local recognition well into the twentieth century, even if active devotion had long since faded. At some point after that, the site was lost entirely to an area of rough, poor-quality pasture, leaving the two map editions as the principal evidence that it existed at all.
