Fairy fort / stone ringfort in Carrownamaddy (athlone South By.)

Fairy fort / stone ringfort in Carrownamaddy (athlone South By.) is a fairy fort or stone ringfort in Carrownamaddy (athlone South By.), County Roscommon, Ireland. It occupies the west edge of a low plateau as a circular grass-covered area measuring forty-four point nine metres east-west and forty-four point eight metres north-south. A stone wall and hedge define the perimeter, preserving greatest height and width toward the southwest while reducing to inner and outer facing-stones toward the northeast. No identifiable original entrance remains, and a northeast-southwest road cuts the eastern-southern boundary.
