Labbyfirmore

Located on a terrace just below the crest of a W-facing slope. It is depicted on the 1834 edition of the OS 6-inch map where it is described in gothic lettering as a ‘Cromlech’ and it is described as ‘Labbyfirmore’ – the bed of the big men – on the 1907 edition. This is a circular grass and furze-covered cairn (diam. c. 20m) with evidence of three cists. One cist consists of a large capstone supported on two long side-stones and one end-stone. A second cist to the SW is roofed by a single large roof-stone supported by six slender upright stones. The third cist is only visible as portion of what might be a roof-stone buried I in the cairn just S of an E-W field bank that overlies the N part of the cairn. 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. Revised by: Michael Moore Date of revision: 9 May 2018

Neolithic passage tomb, dating to approximately 3500–2500 BCE. Its depiction on the 1834 Ordnance Survey map indicates historical recognition as a prehistoric monument, though its wider archaeological significance remains unclear due to lack of detailed study.
