At Breeny More, on a gently sloping platform above the Owvane River valley in west Cork, the answer is unambiguous. Each of those boulders is a cover-stone, propped on smaller support stones to create a low, enclosed space beneath. These are boulder-burials, a monument type particular to the Cork and Kerry region, in which a substantial flat or rounded stone is raised just clear of the ground on a series of squat uprights, forming a kind of compressed chamber. What makes Breeny More unusual is not just the presence of boulder-burials but the fact that there are four of them, arranged as a matched group within a single stone circle.

The site sits within what is classified as a multiple-stone circle, a form of prehistoric monument associated with the Bronze Age in south-west Ireland. The four boulder-burials are disposed symmetrically, two on each side of the circle's main axis, positioned closer to the axial stone, the large recumbent stone that typically marks the south-west of such circles, than to the entrance on the opposite side. The cover-stones are substantial: the largest, to the west, measures 1.8 metres long, a metre wide, and 0.8 metres thick, and is supported by two visible stones at its southern end. The southern cover-stone is even longer at 1.7 metres. Beneath three of the four boulders, the small support stones are still visible; beneath the eastern boulder, none can be seen. The arrangement was documented in detail by Seán Ó Nualláin in 1978, whose survey of boulder-burials in the region remains the primary reference for understanding how the Breeny More group fits into a wider pattern of prehistoric funerary and ceremonial practice across the south-west.
