Holy wells of this kind are among the most quietly persistent features of the Irish landscape, continuing to attract quiet veneration long after the formal religious structures around them have crumbled or been forgotten entirely. That this one carries a name at all suggests it was once a place of some local significance, a site where people came to pray, to leave offerings, or to seek cures in the manner associated with such wells across the country.

Beyond the name itself, the documentary record for Tobertiernan is thin. It appears as a recorded monument in the national inventory of archaeological sites, which places it within a tradition of recognition stretching back through successive surveys of the Irish countryside, but the details of its history, its physical condition, and any pattern of rounds or devotion once associated with it have not yet been fully documented in accessible form. Holy wells were often sites of patterns, seasonal gatherings held on a saint's feast day involving prayers, processions around the well, and sometimes music or assembly, many of which were suppressed or faded during the nineteenth century. Whether Tobertiernan ever drew such gatherings is not currently recorded.
