Located on the broad summit of Coolderry Hill. This is a raised D-shaped and grass-covered area (dims 58m NNE-SW; 46m NW-SE) that slopes down (H 2.4m) to the SE defined by an earthen bank, often reduced to a scarp (at SE: Wth 3m; H 1.5m), and an outer fosse (at SE: Wth of top 7m; Wth of base 3m; ext. D 0.3m) N-SE, with an outer bank (at SE: Wth of base 3.5m; ext. H 0.6m) ESE-S. A NW-SE field bank truncates the monument at SW and a NNE-SSW field bank (at NW: Wth of base 6m; Wth of top 1.5m; int. H 0.6m; ext. H 2.6m) and outer drain (at NW: Wth of base 2m; ext. D 0.9m) truncates it at W. The original entrance (Wth of base 4m) and causeway (Wth of top 6m; H 0.4m) are at E. 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. Compiled by: Michael Moore Date of revision: 12 August 2019 Amended: 24 March 2023
