Fairy fort / earthen ringfort in Killaghteen

Killaghteen holds a broken ring where human hands shaped the earth before memory faded. The measurement is plain: twenty-six metres north to south, twenty-five east to west, with a shallow scarped edge and whitethorn bushes along part of the crest. The meadow has swallowed the rest. What is left is a circle wide enough to walk, quiet enough to forget, and old enough to make that forgetting feel like loss.
