This one, a strong spring at the base of the western slopes of Lateevemore on the Dingle Peninsula, was dedicated specifically to sick horses, which already sets it apart. Its Irish name, Tobar an Chapaill, means simply the Well of the Horse, and the name comes loaded with a warning.

The folklore recorded around this well is unusually layered. The practice of "making the rounds" at a holy well refers to a ritual circuit, typically performed a set number of times, often while reciting prayers, as a form of devotion or petition for a cure. At Tobar an Chapaill, those rounds were made on behalf of ailing horses. But one man, according to the legend noted in the Ordnance Survey Name Books for Kilmalkedar, took the ritual too far and rode the circuit on horseback; both he and the animal dropped dead. A second version of the story, recorded by the folklorist Caoimhín Ó Danachair in 1960, adds a further episode: an Englishman arrived at the well in mockery, leading a blind horse. The horse recovered its sight. The man lost his. The well, in other words, was understood to be entirely capable of distinguishing between genuine supplication and contempt, and of responding accordingly. That combination, an animal cure, a fatal transgression, and a story of comeuppance visited on a sceptic, gives the site an unusually complete narrative architecture for a spring well.
