Fairy fort / earthen ringfort in Killyslavan

Situated at the crest of the NE-facing slope of a drumlin. A circular earthwork is depicted on the revision of the 1834 edition of the OS 6-inch map dated 1858, and it is depicted as a curved field bank surviving SE-W-NW on the 1907 edition. There are faint traces of earthen bank and external fosse surrounding a D-shaped grass-covered area (dims 31.5m E-W; c. 20m N-S). it is truncated by an E-W field bank at N and there is a pole on the bank at SE. Rath (MO003-048----) is c. 30m to the SE. 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. Date of revision: 25 July 2017 Revised by: Claire Breen
