Scattered through the mound are numerous quartz stones, a detail that quietly sets it apart. Quartz appears repeatedly at sacred sites across Ireland, used at passage tombs, wedge graves, and holy wells alike, its white glitter apparently carrying some significance that predates Christianity and lingered into folk practice long afterwards. Here, though, whatever rituals were once observed have ceased entirely. The site is no longer in holy use.

Holy wells were typically tended through a practice known as "rounding", in which a devotee would walk a prescribed number of circuits around the well, often reciting prayers, sometimes leaving offerings such as rags, coins, or small objects on nearby bushes or stones. Many wells were associated with a particular saint and celebrated on that saint's feast day, drawing local people for both devotion and sociability. The well at Kilcoe seems to have belonged to that same broad tradition, positioned with a view out over the bay in a manner that suggests deliberate placement rather than accident. Whether it was ever formally dedicated to a named saint is not recorded, and its small, unadorned form gives little away about the depth or duration of its use.
