What is recorded here

Clermont Carn is a circular hilltop passage tomb in County Louth, Ireland, standing more than 4m high and 21m across. Its narrow chamber, just over 3m long, lies in the south-west quadrant with three lintels still in place and a corbelled rear. Near the centre are remains of a smaller drystone-walled circle, possibly built later by Lord Clermont. The site is a National Monument, preserved for its ancient shape and layered history.

This circular hilltop cairn, 21m in diameter and over 4m in height, contains the remains of a megalithic structure 3.5m long, in the SW quadrant. It is open to the SW and narrows from 1m wide to 0.5m at the rear. Three lintels are in position; the rear 0.7m of the structure is corbelled. The remains would seem to be those of a passage-tomb of uncertain design. Near the centre of the cairn are the remains of a drystone-walled circular structure, 3.3m in diameter, with an entrance passage opening to the SE, which may have been built by Lord Clermont. (CLAJ 1941, 77-9; Herity 1974, 232). This is a National Monument, in state ownership: No. 597. The above description is derived from both the published 'Archaeological Inventory of County Louth' (Dublin: Stationery Office, 1986) and the 'Archaeological Survey of County Louth' (Dublin: Stationery Office, 1991). In certain instances the entries have been revised and updated in the light of recent research. Date of upload: 17 July 2007
