What is recorded here

Crannog in Derrygassan Lower,emy,portinaghy,tiramoan is a submerged cairn in Emy Lough, marked only by a pole one to two metres below the water. It sits where four townlands meet, close enough to the south shore that a person could have waded out at low season. The McKenna leadership may have held this strange underwater room into the sixteenth century, turning a hidden lake into a seat of power.

Located in the rectangular (dims c. 700m N-S; c. 600m E-W) Emy Lough close to the S shore. A crannog is not depicted on any OS map, but the lake and ‘the Island’ are depicted on maps of Co. Monaghan from c. 1590 by Browne and Bocazio, and from c. 1591 and c. 1598 by Jobson. As a high status site it is argued that it could have been occupied by the McKenna leadership into the sixteenth century (McDermott 2010, 400-402, figs 4, 6). This is a submerged cairn (diam. c. 15m), which and it is located at the point where four townlands meet c. 100m from the S shore. It is normally c. 1-2m below lake level but its location is marked by a pole. 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: 29 August 2017
