What is recorded here

No visible fort remains in the Trostan pasture, though a 35m embanked circle appeared on an 1834 map beside Spring Lough. The missing earth may have been taken for fields, or the drawing may have recorded a boundary now forgotten. Either way the place keeps its shape in loss: a room large enough to hold people, animals and weather, now returned to grass.

Situated in a col between drumlins, the summits of which are c. 220m to the SE and c. 600m to the NW, and it is also overlooking the S end of the triangular Spring Lough (dims c. 540m NNE-SSW; 275m NW-SE at SW) which is c. 150m to the NE. It is depicted as an embanked enclosure (ext. diam. c. 35m) described as a ‘fort’ in gothic lettering only on the 1834 edition of the OS 6-inch map. No archaeological feature is visible at ground level in pasture. The rath (MO031-043----) is c. 200m 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: 28 July 2017
