Sites of this kind, called calluraghs or cilliní in Irish tradition, were used to inter those who died unbaptised, including infants, and were generally set apart from consecrated churchyards. This one at Murorgán sits at the south-west corner of a field, bounded on two sides by field walls and on the south by the Murirrigane river, with its eastern side left open to the bay and the wider landscape beyond.

At the centre of that open eastern edge stands a small circular cairn, about three metres across and just over half a metre high, built up with roughly-laid drystone masonry and scattered across its upper surface with quartz pebbles. The use of quartz at burial sites has deep roots in Irish prehistoric and early Christian practice, the white stone carrying associations with the dead and with transition, though whether its presence here reflects very old custom or a more recent folk habit is difficult to say. What complicates the picture further is a dressed slab, discovered at a calluragh in this area by the County Kerry Field Club in 1949, which bore a series of markings the club believed might represent a script. The stone was probably from this site, though possibly from a related children's burial ground at nearby Ballymore. Its current whereabouts are unknown, and without it there is no way to establish whether those markings were a genuine inscription, something natural, or simply accidental. The question has remained open ever since.
