Cornabrassan Fort

Raised almost circular area (int. diam. c. 118.5m) enclosed by a substantial earthen bank from WSW-N-E and a wide, deep fosse. A scarp which appears to be natural in part runs from S-WSW. Bank is breached at SSE and NW and one of these breaks probably represents the original entrance. The site is situated in low-lying ground, bounded by a swamp from SE-S-WSW, and overlooked by higher ground. The above description is derived from the published 'Archaeological Inventory of County Cavan' (Dublin: Stationery Office, 1995). In certain instances the entries have been revised and updated in the light of recent research. Date of upload/revision: 22 December 2008

Cornabrassan Fort on Inishmore is a well-preserved early-medieval ringfort, likely dating to between the 6th and 10th centuries AD, characterized by a large circular enclosure with a substantial earthen bank and fosse. Local tradition associates such sites with the Tuatha Dé Danann, and Inishmore's forts are often linked to Arán, a legendary giant said to have built many of the island's earthworks.
