Fairy fort or earthen ringfort in Coolnagun

Situated on low rise of poorly drained land with stream immediately to W. Ringfort (WM002-022---) 175m to NNE, ringfort (WM002-021----) 85m to SW. partially depicted on the 1837 ed. OS 6-inch map where a quarry is shown on the W side of the earthwork. A second quarry is also depicted a few metres to the S of the earthwork on the 1837 ed. OS 6-inch map. On the revised 1911 ed. OS 25-inch map a rectangular building is shown in the SSW quadrant of the earthwork in the area where the quarry was marked on the 1837 ed. OS 6-inch map. The enclosing element on the W half of monument has been quarried away. Present remains consist of a large sub-triangular shaped area (dims. 72m NNW-SSE; 54m WSW-ENE) defined by an earth and stone bank (Wth 6-7.8m; int. H 0.3-1.2m; ext. H 1.9m) visible from N-E-SSE only elsewhere it has been reduced to a scarp (H 0.8-1.4m) and external fosse visible from N-E-SE only. No entrance feature visible. A rectangular-shaped flat-topped mound (13m NNW-SSE; 10.4m WSW-NNE; H 0.8-1m) in the W quadrant of the interior could be post 1700 upcast from quarrying activities along W edge of monument. There is a small rectangular enclosure (house site) (WM002-023001-) on the upper edge of the scarp on the N. In the NW quadrant close to the scarp a small sub-rectangular area delimited by an embankment of earth and stone may possible represent a house site. In the N quadrant a low earth bank extends across the interior as a form of partition delimiting a sub-rectangular area. Old cultivation ridges in evidence in SE quadrant of interior.
