The infrastructure dated to the eighteenth and nineteenth centuries and had been built specifically to serve a holy well dedicated to Saint Fiachra, allowing crowds to approach the site without sinking into the mud on his feast day.

The well itself sits on the west bank of the River Nore, enclosed by a stone wall and covered by a flat stone lintel over its entrance. A Calvary, a sculptural grouping representing the crucifixion scene, was erected at the well around 1930, adding a layer of twentieth-century devotion to a site with much older roots. Writing in 1905, the historian Carrigan described it as a celebrated holy well where public devotions were held annually on Saint Fiachra's day, the 30th of August, though he noted that practice had lapsed by his time. Saint Fiachra himself was a seventh-century Irish monk who later founded a monastery in France and became associated in particular with gardens and horticulture, a patronage that gave his name a wide following across Catholic Europe. The pattern, an Irish term for a gathering held at a sacred site on a patron saint's feast day, combining prayer with communal activity, was clearly a significant occasion here: the cobbled access works uncovered in 1983 indicate sustained effort over two centuries to keep the site functional for large numbers of visitors.

The well lies roughly sixty metres southeast of Saint Fiachra's church and its associated graveyard, placing it within a small cluster of related sites. The cobbled surfaces and trackway discovered during the pipeline excavation are no longer visible, but the well retains its stone enclosure and lintel, quietly marking a landscape that was, for a long time, a destination rather than simply a place people passed through.
