The National Monuments Service's description
Located just E of the summit of a hill in an undulating landscape. This is a subcircular overgrown area (dims 35.4m NW-SE; 29.5m NE-SW) defined by an earthen bank (at S: Wth of base 4.9m; int. H 0.6m; ext. H 2.3m), accompanied by a fosse W-NNW. There is an entrance (Wth of base 2.3m) at SSE. The interior had been cleared and the perimeter NW-E-SW removed by 1995 (OSAP).
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.
