Fairy fort / earthen ringfort in Shanrath

Fairy fort in Shanrath, County Limerick: a 27m earthen ring now flattened to a faint pale circle in pasture, its ditch reduced to a shallow smile the field boundary cuts through. People called it fairy fort because the shape appeared and vanished like breath on grass, yet the ring is human-made and the field has walked over it. What is left is enough to see: a circle, a shade of a ditch, and the certainty that living things once drew that line and stopped at it.
