It is a square, shallow depression filled with water, unadorned by formal stonework or enclosure. What makes it worth pausing over is what surrounds it: rough crosses and a harp incised into the rock face nearby, markings that speak to long use and quiet, persistent devotion rather than any single moment of official commemoration.

The well is known locally by two names, either "the blessed well" or St Mochuda's Well, the latter connecting it to one of the more widely travelled saints of early Irish Christianity. Mochuda, also known as Carthage, was a sixth and seventh century figure associated principally with Lismore in County Waterford, though his name surfaces across Munster in dedications to springs and churches that suggest a broad sphere of influence long after his death. Holy wells, typically natural or rock-cut sources of water believed to carry healing or protective properties, were woven into pre-Christian landscape practice and later absorbed into Christian devotion; many retain their patron saint's feast day as the occasion for "patterns", the local term for a day of prayer, circumambulation, and ritual at the site. The incised carvings at Drumlave, rough rather than refined, have the feel of marks made over time by different hands rather than by a single craftsman, which in itself tells a story about cumulative, informal veneration.

The well is recorded as still venerated, meaning it has not faded into the category of purely archaeological curiosity. The carved harp is a relatively unusual motif in this context and worth looking for closely once you locate the well; it sits among the crosses in the surrounding rock surface rather than within the well itself.
