What makes this place quietly peculiar is a detail preserved in local tradition: two natural pools that formed at the external base of the wall, on the north-western side, were known simply as "the eyes". People suffering from eye ailments would come here and bathe their eyes with the water, believing it to have curative properties. The naming is not purely poetic. The pools, shaped and positioned as they are, apparently resembled a pair of eyes set into the face of the wall, and the association between their form and their supposed function became fixed in local memory.

The well itself is a modest construction, a subcircular enclosure of drystone walling interspersed with trees, with a southern entrance. Drystone construction, which uses no mortar and relies entirely on the careful arrangement of stone, was common for such enclosures, though the walling here has been described as poorly built, and by the time of inspection it was already showing signs of collapse near the entrance. Tree roots were pressing into the foundations. A reference recorded by O'Flanagan in 1927 confirms the well was known and documented in the early twentieth century, and the name Tobernahaulue itself, from the Irish tobar, meaning well, roots it in the wider tradition of sacred springs that were central to local religious and healing practices across Ireland for centuries. Immediately to the south-west of the well lies a children's burial ground, a type of site known in Irish as a cillín, where unbaptised infants were historically interred in unconsecrated ground, separate from parish cemeteries. The proximity of the two sites, the healing well and the burial ground, places this small hillside within a landscape that was once understood as genuinely set apart.
