Clermont Carn (Irish: Carnán Mhaighréid Náir, meaning 'cairn of noble Margaret'),[1] also known as Black Mountain, is a mountain that rises to 510 metres (1,670 ft) in the Cooley Mountains of County Louth, Ireland. It is at the border with Northern Ireland, and is also the location of the Clermont Carn transmission site. The mountain's name refers to an ancient burial cairn on its summit, and to Lord Clermont of Ravensdale.[1]

It has been suggested that Clermont Carn transmission site be merged into this article. (Discuss) Proposed since August 2022.

Cairn

The 'carn' in the mountain's name refers to an ancient burial monument on its summit,[2][3] also known as 'Black Mountain Chambered Cairn' or 'Ravensdale Park Cairn'. This cairn is 21 m (69 ft) in diameter and over 4 m (13 ft) high, with the remains of another trapezoidal cairn 3.5 m (11 ft) long in the southwest part. Three lintels are in position and the rear part is corbelled. Surrounding this was a court (5.5 × 7 m) and a gallery containing at least two burial chambers.[4]

It was built in the early Neolithic, c. 4000–3500 BC, and forms part of the Clyde-Carlingford group of court cairns. In recent decades the site has been disturbed by quarrying and blasting.[5][6] It is a protected National Monument.[7][8]
