A small concrete shelf built into the south-west corner still receives offerings, and two steps lead down to the water through a turnstile gate, giving the whole structure a quietly functional, devotional quality that larger shrines rarely manage.

The well appears on the Ordnance Survey six-inch map of 1839, labelled in gothic lettering as "Lady's Well", and the same lettering appears on the 1940 edition, suggesting a continuity of recognition across a century. John O'Donovan, the meticulous nineteenth-century scholar who travelled Ireland documenting its place names and antiquities, noted around 1840 that the well was dedicated to the Blessed Virgin and formed part of the local pilgrimage associated with Lady's Island. A later account, drawn from the memory of an elderly resident and recorded by Mac Leighim in 1920, adds that the pattern, the Irish term for a devotional gathering at a sacred site, was held on the feast of the Assumption, the 15th of August, and that the pilgrimage route culminated here at the well. At some point the well's shape changed: earlier descriptions record it as coffin-shaped, a form found at other Irish holy wells and thought to carry associations with death, resurrection, and spiritual renewal. The current rectangular basin, measuring roughly 1.2 metres by 1.1 metres, is what survives today, enclosed on three sides by a low concrete wall.

The well sits on level ground along the eastern shore of Lady's Island Lough, with the lake itself lying about 75 metres to the west. Archaeological monitoring carried out nearby to the north-east found no related features beneath the surface, leaving the well as the principal visible trace of what was evidently a well-used devotional landscape.
