They are bullaun stones, a type of worked or naturally hollowed boulder associated with early medieval religious practice in Ireland, their distinctive cupped depressions used variously for grinding, for ritual, or perhaps both. The largest of the three measures just 0.44 metres by 0.33 metres, only 0.08 metres thick, with an oval hollow worn or cut into its surface to a depth of 0.06 metres. It is a modest object by any measure, and that modesty is part of what makes it worth pausing over.

The site itself is recorded under the Irish name Cill na gColmán, meaning the church of the doves or of Saint Colmán, a designation that points to early Christian settlement in a landscape already dense with pre-Christian monuments. The three bullaun stones were originally found at different locations across the site before being consolidated and set in front of the ogham stone, an upright pillar inscribed with the early medieval script known as ogham, which uses a series of notches and strokes along a central line to record names and phrases, most often in an archaic form of Irish. Grouping the bullauins before the ogham stone gives the arrangement a certain deliberateness, though it is an arrangement of relatively recent curation rather than original placement. The site's details were first systematically recorded by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a foundational document for the archaeology of this part of Kerry.
