This ring of 13 standing stones is the finest example of a megalithic stone circle in County Cork. The circle dates from 153 B.C., and little is known about its ritual purpose. However, the remains of two huts and a cooking area, just to the west of the circle, give some clue; it is thought that heated stones were placed in a water trough (which can be seen adjacent to the huts), and the hot water was used for cooking. This section has been dated to sometime between A.D. 368 and 608.
