Fairy fort or earthen ringfort in Mountain Common

In pasture, located on a NW–SE ridge. The ground shelves away steeply for 160m to SW to the shore of Mannin Lake. Slightly raised, broadly oval area (31.5m N–S; 35.6m E–W) defined by a partly levelled scarp (H 0.6m), outside which it is enclosed by a fosse (Wth 2.2m at SW) with remnants of an external bank (Wth 2.6m; int. H 0.6m; ext. H 0.7m, at SW). The central platform is relatively level and appears to have been built up on the W half to compensate for the natural fall of ground to NW and SW. The fosse is evident as a shallow depression. The external bank survives at S–NW as a low, dilapidated earth and stone bank; it is levelled at NNW–NE to a slight surface undulation; it is subsumed at ENE–SE into a field fence which preserves the curve of the rath and at SSE–S is levelled to a barely discernible surface rise. Grass cover, with hawthorn bushes around the perimeter.
