Holy wells in Ireland typically accumulate local lore, patron saints' days, and customs of votive offering over centuries. This one, named Tobar Mhartáin, or Martin's Well, carries none of that. No pattern day, no rags tied to a nearby bush, no passed-down story of a cure. The label remains; the tradition does not.

The Ordnance Survey recorded the well as early as 1840, and by the 1916 edition it had been given the anglicised name Tobermarteen. Doolan, writing in 1991, listed it as a blessed well opposite Leamaneh Castle, which places it squarely within a landscape already remarkable for its architecture. Leamaneh itself is one of the more striking tower house and fortified house complexes in the Burren, its ruined façade familiar to anyone who has driven the road between Kilfenora and Carron. The well lies some 60 metres to the south-east of the castle, just beyond the boundary of its walled garden. Physically, it is a substantial construction: a trapezoidal enclosure roughly 2.7 metres east to west and 2.4 metres north to south, sunk to about a metre in depth, with drystone walls, one of which curves at the eastern end. A large covering slab seals it over. Its most practical function may have been entirely secular; the well appears to have supplied water to the fish-ponds that once operated within the walled garden to the east, a common enough arrangement on estate properties of the period, where a reliable spring would have been a working asset rather than a site of veneration.
