Fairy fort / ringfort in Balrickard

Fairy fort in Balrickard, County Dublin: a hidden ring under pasture, recorded in a 1972 aerial photograph as a level circular shadow about twenty-two metres wide. The field also held a quarry on older maps, so human hands may have broken the ring before it vanished beneath grass and traffic. What remains is a ghost shape in the soil, waiting for rain or drought to draw its line again.
