Roughly a metre tall and broadly heart-shaped, it is called both the Heart Stone and Cloch na gCursa, meaning the Stone of the Rounds, and it marks the starting point of a ritual circuit still observed on July 25th each year.

The rounds in question are a form of devotional circumambulation, a practice common at Irish holy sites in which a set number of circuits are made around a sacred spot, often accompanied by prayer. Here the circuit begins at the stone, following mass in the burial ground, and continues around the nearby holy well of St Laserian. The stone itself is associated with a separate figure: according to local tradition and the antiquarian James Grove White, writing in the early twentieth century, it marks the grave of a person known as Lateerin, and is locally called St Laterian's Stone. The pairing of two saints at a single site is not unusual in the Irish tradition of sacred landscape, where wells, stones, and burial grounds often accumulated layers of association over centuries. Bowman, writing in 1934, recorded the Irish placename that captures the stone's ritual purpose rather than its funerary one, suggesting that by then its role in the annual rounds was the detail most alive in local memory.
