Fairy fort / earthen ringfort in Derrylea Beg

Located on a knoll towards the bottom of a N-facing slope and overlooking a small S-N stream c. 30m to the W. This is a subcircular grass and scrub-covered area (int. dims 30.4m NE-SW; 26.2m NW-SE) defined by an earthen bank with traces of an external fosse, most visible at S and N (Wth of top 3m; Wth of base 1.6m; ext. D 0.2m). An entrance (Wth of base 2.2m) with traces of a causeway at NNE might be the original entrance. 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: 25 July 2017
