What remains is a small circular hole, blocked with rubble, sitting inside a roofless rectangular enclosure built from limestone flags set upright on their edges. The enclosure measures roughly eight metres by seven, and the well occupies its southern portion. It is the kind of site that asks you to do a good deal of imaginative work.

In 1886 a writer named Barry recorded it as a dripping well, calling it "Tobarchora", though the correct Irish form is Tobar Charna, meaning the well of Carna or, more likely, of a saint associated with this locality. The well sits approximately two and a half metres north of a structure identified as a possible early church, the two features together suggesting a small sacred complex of the kind that was once common across the west of Ireland, where a holy well and an oratory or church would occupy the same enclosure or stand in close proximity. Holy wells in Ireland were typically venerated as places of healing, prayer, and patterns, the latter being seasonal gatherings involving circumambulation of the site, often on the feast day of the associated saint. The drystone enclosure, with its limestone flags set on edge rather than laid flat, is a building technique well suited to the island's geology, where limestone is abundant and timber scarce. Whether Tobar Charna ever attracted significant pilgrimage is not recorded, but its modest scale and careful construction suggest it was a place that mattered to people in the locality for a long time.
