An axial five-stone circle is a particular type of megalithic ring of five stones of which many are found in southwest Ireland. These circles have an approximate axis of symmetry aligned in a generally northeast–southwest direction – the stone at the southwest side of the circle, rather than being an upright orthostat like the rest, rests on the ground with its long axis horizontal. Because it marks the axis it is called the axial stone. It is usually quite thin and it lies with its long thin edge along the circumference of the ring.[1][2]
Early in the 20th century this type of circle was called a recumbent stone circle by analogy with similar examples in Scotland but when it became clear there were substantial differences the term "Cork–Kerry stone circle" was used for both types until later the term "axial stone circle" became commonly used.[6]
Ó Nualláin (1984) has published a comprehensive catalogue of stone circles in the two counties and Burl followed with two books, Burl (1995) and Burl (2000), covering a much broader area but still including this type of circle. Ireland's National Monuments Service, part of the Department of Culture, Heritage and the Gaeltacht, operates a database of archaeology sites and the list in this article covers the sites classified as "stone circle – five-stone".[7] The NMS definition is:
Stone circle - five-stone
A distinctive form of stone circle found only in counties Cork and Kerry. It comprises a ring of five free-standing stones, symmetrically arranged so that one stone, the axial stone, is set directly opposite two stones, usually the tallest, marking the entrance to the circle. Characteristically, the stones reduce in height to the axial stone, which is set consistently in the south-western part of the circle. These circles are thought to have a ritual function and are dated to the Bronze Age (c. 2400-500 BC).
