Fairy fort / ringfort in Deerpark (shillelogher By.)

Deerpark holds a circular fort thirty metres across, ringed by an eight-metre ditch that human boundaries still bend around instead of cutting through. Trees have strangled the entrance and pasture grass has swallowed the inner floor, yet the shape remains clear enough for surveyors to draw twice across a century. The fairies may have taken the people, but they left the geometry behind.
