The one at Dunbeacon in west Cork breaks both conventions quietly. It is square, roughly two metres across, and its name gestures not towards any holy figure but towards an everyday crop. Toberaleen, or Tober a'Lin, translates from the Irish as the well of the flax, a name that roots the place in agricultural life rather than devotional practice.

Flax cultivation was once common across Ireland, grown for the linen industry and for domestic use, and a reliable water source would have been practically valuable to those processing the plant. The well is said never to run dry, which in a working landscape would have made it worth knowing about. A stream flows from the depression, suggesting the spring feeding it is consistent enough to earn that reputation. At some point the site did acquire the status of a holy well, the category under which it is formally recorded, though it is no longer visited for religious purposes. Exactly when or how it moved between those two identities, the purely practical and the sacred, is not documented. The local name recorded by O'Donoghue in 1986 preserves the older, more earthly association, suggesting the flax connection predates whatever devotional use the site once saw.
