Set into the sloping ground in an apsidal form, the well's vaulted roof stones are now partially exposed by erosion, and its front façade has suffered damage over time. What survives on the west side, however, includes something genuinely odd: two dressed stones from the arch of a 15th-century ogee-headed window light. An ogee arch is a sinuous, pointed form common in late-medieval Irish ecclesiastical and defensive architecture, and these particular stones carry the characteristic deep outer chamfer and shallower inner chamfer of that tradition. One remains in place in the façade; the other lies loose beside the well. Both are carved with the date 1788, almost certainly marking when the well surround was constructed, using whatever salvaged material was available.

The stones are the real puzzle. They almost certainly came from a tower house, the compact fortified residences that were built across Munster in their hundreds during the 15th and 16th centuries. Yet no castle is recorded at this location on Ordnance Survey maps, and there is no local tradition or surviving information identifying the source building. Whoever commissioned the well surround in 1788 had access to finely worked late-medieval stonework and made deliberate use of it, incorporating the old arch stones at the upper ends of the façade in a way that gives the structure a vaguely formal appearance. A short distance to the north stands a folly building that contains reused dressed stone of the same 15th-century style, and the two structures are thought to have been built at the same time, part of the same exercise in repurposing material from a vanished original. The well itself carries no tradition of veneration and appears to have been secular in function throughout, which makes the care taken in its construction all the more curious.
