What is recorded here

Overgrown grass and soil mark a thirty-three-metre ring on a steep Monaghan drumlin, yet the earthen bank, narrow entrance and broad outer edge still shape the land. It has stood since before human memory in local thought, and perhaps people once lived inside its double rim while believing the fairies owned the hill. The fort resists easy explanation because it is both an ordinary home and a sacred boundary, visible on old maps but hidden beneath green growth.

Located on top of a steep-sided drumlin. This rath is represented on McCrea’s Map of County Monaghan (1793) and on the 1834 and 1907 editions of the OS 6-inch map. It is a raised and slightly domed but overgrown area (diam. 33m E-W; 32.5m N-S) defined by an earthen bank separated by a fosse from a broad outer bank (Wth of top 4.8-6.3m) that has a narrow bank, perhaps a field bank, on its outer edge. At the foot of the outer bank is a distinct berm. There is an entrance (Wth of base 2.5m) and causeway (Wth of top c. 3m; H 0.4m) 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. Revised by: Michael Moore Date of revision: 19 June 2018

A fairy fort or earthen ringfort in Lisnagalliagh, likely dating to the early medieval period, is situated on a steep-sided drumlin and has been mapped since at least 1793. Local tradition associates such sites with fairy lore, and they were often avoided due to beliefs in supernatural inhabitants.
