Its upper surface holds a shallow circular hollow, roughly sixteen centimetres across and six centimetres deep, worn or carved into the rock in a form known as a bullaun. These cup-shaped depressions, found on stones across Ireland, are associated with early Christian and pre-Christian ritual; the water that collects in them was traditionally considered to have curative or sacred properties, and the stones were visited as part of acts of devotion or penance.

What makes Scronagare particularly interesting is that this stone does not stand alone. It measures approximately 0.46 metres by 0.37 metres and sits at the south-eastern edge of a mound identified as a penitential station, a site where people would once have performed circuits of prayer, often on their knees, following a prescribed devotional route. A second bullaun stone sits atop the same mound nearby. The combination of two bullauns within a single penitential complex, one at the base and one at the summit of the mound, suggests a site that was structured around movement and repeated ritual contact with these stones, rather than passive veneration from a distance. The mound itself, as a focus for organised penance, points to a tradition of localised religious practice that persisted in rural Ireland well beyond the early medieval period.
