Fairy fort / earthen ringfort in Lisgrew

: Located at the N end of a NNW-SSE drumlin ridge. This is a circular overgrown area (diam. 30.4m WNW-ESE; 28m NNE-SSW) that slopes down slightly to the N, which is defined by an earthen bank (Wth 1m) separated by a fosse (Wth 2m) from a larger outer bank (Wth 3m) and second external fosse (Wth 2m), although the external fosse is absent N-E. There are entrances at SW and N, but the original entrance through the inner (Wth 4.6m) and outer (Wth 3.1m) banks with causeways over the inner (Wth 4m) outer (Wth 4m) fosses and is at ESE. 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
