The well itself is modest, a stone-lined circular shaft just 1.3 metres in diameter, but it sits within an enclosing circular wall topped with a corbelled roof, a construction technique in which stones are layered inward and upward without mortar until they meet at the top, forming a self-supporting dome. The entrance faces north, and a visitor descends roughly 0.7 metres via steps cut into the structure to reach the water. That combination of corbelled roofing and below-ground access gives the whole thing the quality of a small, self-contained chamber rather than a simple outdoor feature.

What lifts the site beyond the purely architectural is the evidence of continuous devotion built directly into the stonework. Three cross-shaped recesses are cut into the external face of the enclosing wall, and on the interior, matching rectangular recesses hold statues and votive offerings. Votive offerings at Irish holy wells typically include medals, rosary beads, rags, or small personal objects left by those seeking intercession or giving thanks, and the recesses here suggest the structure was designed with that practice in mind from the outset rather than adapted to it over time. The combination of deliberate architectural provision for worship and the accumulation of objects left by individual visitors gives the well an atmosphere that is both formal and intimate.
