It sits enclosed by a large rock and the remains of a masonry wall, modest enough that you could walk past it without a second glance. Yet the Irish name recorded on the revised 1913 Ordnance Survey map, Tobermíonad, signals something older at work. Tobar is the Irish word for well, and this particular well has been known locally for generations as St Meenan's Well.

A pattern, the traditional Irish gathering held at a holy well on a saint's feast day, typically involved prayers, processions, and socialising, often all at once. Folklore collected from Rathwire National School and preserved in the Schools' Collection records that in a place referred to as "ancient Glon", in a field belonging to a C Connor, such a pattern was held on the first Sunday of August each year. The well itself is one of two natural springs in the limestone here, both feeding the same southward-running stream. By the early 1970s, when the site was formally described, the enclosing masonry wall was already ruined, though the large rock and the spring itself remained.
