Fairy fort / earthen ringfort in Glasmullagh

Situated just N of the summit of a N-S drumlin ridge. This is an overgrown subcircular area (int. dims 43m NNE-SSW; 38.4m WNW-ESE) that slopes down slightly to the NE, which is defined by an overgrown earthen bank N-ENE and SE-SW, but the perimeter is reduced to a scarp elsewhere. There are tree-stumps in the interior, and there is an outer drain which may be a re-cut fosse. There is an entrance and causeway, which may be modern, at N. 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
