Situated on a NE-facing slope and in a part of Oldcastle townland that is called Portshanmore – the ‘big old bog’. This is a circular grass-covered area (diam. 32m E-W; 30.5m N-S) defined by an earth and stone bank (Wth c. 4-5m; int. H c. 0.3m; ext. H c. 1.5-2m) with some bushes that is incorporated into a field bank N-SE, and the remains of an outer fosse SW-N. The original entrance is probably that (Wth of base 1.8m) at ESE.
The above description is derived from the published 'Archaeological Inventory of County Meath' (Dublin: Stationery Office, 1987). In certain instances the entries have been revised and updated in the light of recent research.
