Fairy fort / earthen ringfort in Rinneen (inchiquin By.)

No human has broken the continuous earthen circle at Rinneen, although cows have walked it for generations and people have called it a fairy fort. The unbroken ring stands on a slight rise above Lough Atedaun, enclosing pasture rather than resisting invasion. Its perimeter measures thirty-nine to forty metres, broad enough for several people to walk abreast and tall enough to mark a boundary without excluding sight. The great eastern stone may have been carried from the lake shore when the water stood higher, set into the bank as a pledge between the field and the drowned land.
