The well sits within a circular drystone enclosure just 1.6 metres in diameter, entered through a narrow gap on the eastern side. Inside, in the western sector of that tight circle, the spring itself has been given a stone-lined rectangular form. It is a modest arrangement, easy to overlook, but the care invested in its construction suggests it has long held significance beyond the merely practical.

Holy wells are among the oldest continuously venerated features in the Irish landscape, typically associated with local saints or with pre-Christian water cults that were gradually absorbed into Christian practice. The drystone enclosure here, built without mortar, is a technique with deep roots in the west of Ireland, where good stone was plentiful and lime-based mortar less commonly used in vernacular construction. The proximity to the castle, roughly 40 metres to the northwest, raises quiet questions about the relationship between the two structures. Whether the well predates the castle, or whether the castle was deliberately positioned near an already-sacred spring, is not recorded, but the pairing is not unusual in the Irish countryside, where secular and sacred sites frequently cluster together across the same ground.
