What makes it quietly unusual is not the shrine itself but the logic attached to it: the well is said to cure sore eyes, and those who are actually cured are granted a sign, the sight of a trout moving in the water below. Those who look and see nothing, presumably, must keep looking.

The folklorist Caoimhín Ó Danachair recorded the well in 1955, noting that it appears on the Ordnance Survey map of 1840 under the name Toberreendoney. Tobar in Irish means well, and the name likely incorporates a personal or devotional element now difficult to untangle with certainty. Ó Danachair noted that devotions were still being made at the time of his writing, though less frequently than in earlier generations, a pattern common to many such sites across Ireland as the more formal patterns, the communal annual gatherings centred on holy wells, gradually fell away through the twentieth century. The well is generally said to be dedicated to Our Lady, and the small statue in its wooden niche reflects that dedication plainly enough. A separate legend accounts for the well's local nickname, "The Black Dog", a name that comes from an apparition of a black dog said to have appeared at the site, though Ó Danachair recorded no further detail about the circumstances or meaning of that appearance.

The well is on the roadside, which means it is relatively accessible without any particular approach through fields or difficult terrain. The stone lining of the well is the most structurally notable feature to look for, a construction method used to stabilise the well shaft and keep the sides from collapsing, common in Irish holy wells of this kind. The wooden niche and cross are modest, the sort of vernacular religious object that weathers quickly, so what is visible today may differ somewhat from what Ó Danachair described in the mid-twentieth century. There is no pattern day formally recorded here, but visitors who take an interest in the folklore of eye cures and curative waters will find the site a quietly legible example of how local legend, devotional practice, and landscape have remained knotted together at particular spots across rural Ireland.
