Set into a south-facing slope of rough grass and heather, it presents itself as little more than a roughly circular pit, less than a metre across and a metre deep, its dry-stone lining partially covered by a loose capping of boulders. When it was inspected in 2006, the well was dry, which lends the site a quietly melancholy character: a vessel built for something it no longer contains.

Holy wells in Ireland were typically focal points for local devotion, associated with particular saints and visited on pattern days, occasions when communities would gather to pray, walk a prescribed circuit, and leave offerings. This one sits approximately twenty metres south-west of a cashel, a type of stone-walled enclosure used in early medieval Ireland to define a settlement or ecclesiastical boundary, suggesting the well was once part of a broader complex of early Christian activity on the island. Duvillaun More carries other traces of this period, and the proximity of the well to the cashel points to a landscape that was once purposefully organised around religious use, however remote and windswept it appears today.
