Tobercalliagh, sitting in a gap in a field wall on the eastern side of a road outside Ballinderreen in south Galway, has none of that. No saint claims it, and no votive offerings have been left at its edge. It is simply a spring well, modest in its dimensions, covered by a stone slab laid across a wooden beam that spans the breach in the wall. The name itself, Tobercalliagh, combines the Irish word for well, tobar, with cailleach, a term usually referring to an old woman or hag figure with deep roots in Irish mythology and landscape lore. That association places the well in a pre-Christian imaginative world, though the well today gives little away.

The well is small, measuring roughly 1.6 metres in length, just over a metre wide, and under two thirds of a metre deep, and it is prone to flooding. It appears under its current name on the Ordnance Survey six-inch maps, the large-scale surveys produced across Ireland from the 1830s onwards, which suggests the name and the site were already established features of the local landscape by the time those maps were made. The stone-and-timber covering looks like a practical solution to protect the water source and to bridge the gap where the field wall was interrupted, but it also gives the well a quietly functional dignity, the kind of low-key care that speaks to long, habitual use rather than any formal commemoration.
