This one in Ballydonohoe comes trailing nothing. Tobar Buí, the yellow well, sits in the corner of a field as a marshy hollow, covered over by the landowner at some point in recent decades, its outline still faintly readable in the ground if you know what to look for. No tradition survives around it. No rounds were walked, no cures recorded, no saint claimed it. It is a named place that has quietly emptied of everything except its name.

The name itself appears on the Ordnance Survey maps of 1840 to 1841 and again on the 1914 edition, which tells us the site was considered worth recording across at least two generations of mapping. Tobar Buí translates from the Irish as yellow well, a colour designation that most likely refers to the mineral content or the appearance of the water, though what precisely gave it that character is no longer known. Immediately to the south-west lies a rath, the remains of a circular earthwork enclosure of the early medieval period, typically used as a farmstead. The proximity of a well to a rath is not unusual in the Irish landscape; water sources and settled enclosures tended to cluster together, and many such wells later acquired religious or folkloric significance during the early Christian centuries. Here, if that process ever began, it left no trace.
