This small stone circle was re-discovered in 1995 when the Sheeps Head Way was being developed. The Archaeological Inventory for County Cork gives the number of stones here as 11 and several are fallen or knocked down. Two large portal stones lead the way in. To the east of the circle is another colossal but now fallen stone - maybe a marker stone - as this would clearly have been seen from the sea. There are also the remains of two possible boulder burials. One can be seen in the NW area of the circle and another may lie just outside the circle as you come in from the south. It is assumed to be aligned NE-SW, possibly marking the mid-winter solstice on the 21st December. Almost directly across Dunmanus Bay is another similar stone circle at Dunbeacon.
