The National Monuments Service's description
Located at the crest of the S-facing slope of a WNW-ESE drumlin ridge towards its W end. This rath is depicted 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 grass and scrub-covered circular area (diam. 27m) defined by an overgrown earthen bank (Wth c. 3m; int. H 0.4m; ext. H 2.1m) with slight traces of an outer fosse. The entrance, now blocked, is at N. The monument is cut by a NW-SE field bank and drain towards the perimeter at NE but still survives outside it.
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.
