What lifts it above a simple water source is the cluster of carved stones arranged around its perimeter: an early Christian cross-inscribed slab, a triangular 18th-century headstone, a late medieval bust, and a crucifixion slab. The bust and the crucifixion stone carry the same carved inscription, blunt and unambiguous: "Repent do Penance." Holy wells in Ireland were traditionally sites of pattern days, local devotional gatherings combining prayer with communal ritual, and the accumulation of stonework here reflects centuries of that layered use.

The well is dedicated to St Ciarán, the founder of the great monastery at Clonmacnoise, whose death is recorded in the annals at 549 AD. Dedication to a founding saint is common at such sites, though the physical structure of this well turns out to be considerably younger than the devotion it attracted. Excavation carried out in 2004, in advance of partial reconstruction work, found that the well had been cut into natural boulder clay and gravels, and that the structure itself was post-medieval in origin. The finds recovered from its fill were mainly coins, dating to the 19th and 20th centuries, the kind of votive deposit familiar from holy wells across the country. References in published sources go back at least to Cooke writing in 1875, and to Monahan in 1886 and Molloy in 1950, suggesting the site had a recognised presence in local and antiquarian awareness long before formal archaeological attention arrived.
