Whilst its precise location remains undiscovered in modern surveys, historical records from Ó Muirgheasa’s collection (No. 64) confirm its existence and cultural significance to the area. The site represents one of many such sacred water sources scattered throughout Donegal, where pre-Christian reverence for natural springs merged seamlessly with later Catholic devotional practices.

Holy wells like this one in Killygarvan Upper typically attracted pilgrims seeking cures for various ailments or hoping to receive blessings through ritual observances. Local tradition would have dictated specific days for visiting, often coinciding with the feast day of a particular saint, though the patron saint associated with this particular well is no longer recorded. Visitors would have performed rounds; a series of prayers whilst walking clockwise around the well, sometimes leaving small offerings such as rags tied to nearby trees or coins placed on stones.

The documentation of this site comes from the comprehensive Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983. This survey catalogued field antiquities spanning from the Mesolithic period through to the 17th century, preserving knowledge of sites that might otherwise be lost to memory. Though the exact spot of this holy well awaits rediscovery, its inclusion in both the archaeological survey and earlier folklore collections ensures its place in Donegal’s rich tapestry of ritual landscapes.
