Fairy fort / earthen ringfort in Longfield Otra

Situated on a broad WNW-ESE ridge. It is depicted as a D-shaped feature (dims c. 40m NNE-SSW; c. 25m WNW-ESE) truncated by a NNE-SSW field bank at W and described as a 'fort' in gothic lettering only on the 1834 edition of the OS 6-inch map. It is visible as a slightly raised and grass-covered circular platform (diam. 36.4m NE-SW) divided by a NNE-SSW field bank and also by a WNW-ESE field bank and path. There is no visible fosse or entrance, but the perimeter is most clearly visible NE-SE. The above description is derived from the published 'Archaeological Inventory of County Monaghan' (Dublin: Stationery Office, 1986). In certain instances the entries have been revised and updated in the light of recent research. Date of revision: 28 July 2017
