The holy well consists of a natural spring partially enclosed by a low stone cairn, though its exact location has proved elusive; even the Ordnance Survey maps of the 19th century appear to have marked it incorrectly, which likely explains why the Archaeological Survey of Donegal initially struggled to locate it. Whilst votive offerings of rags were recorded here as recently as 1976, no traces of these ritual deposits remain visible today.

This sacred spring is one of several holy sites that together form the turas, or pilgrimage circuit, of Templecrone. The route encompasses two wells on the mainland; Toberfinan and Tobercrone, located 240 metres to the east; alongside a holy stone with curious finger-like impressions, and the medieval church and graveyard of Templecrone itself. Local tradition holds that a third well on the island of Illancrone, some 2.1 kilometres west, also formed part of this sacred journey. An old stone-walled track running east to west, marked on historic Ordnance Survey maps and still visible 40 metres north of Toberfinan, appears to be the original pilgrim way.

The turas was traditionally performed on 7th July, the feast day of St Chróine, patron saint of Templecrone church. Pilgrims would recite seven Our Fathers and seven Hail Marys at each holy well, repeat the prayers at the cairn near the churchyard, and maintain a continuous recitation of the rosary whilst traversing the circuit. The portable holy stone, bearing its mysterious finger marks, held particular significance for healing rituals; families experiencing illness would borrow the stone overnight, always returning it to its exact position by morning. According to local lore, eleven bishops lie buried at this site, and the tradition of making the turas continued well into the 20th century, with devoted pilgrims still seeking the blessings of St Chróine’s sacred landscape.
