Knocklayd (Irish name: Cnoc Leithid, "hill of the slope/expanse"[1]) is a peak in County Antrim, Northern Ireland, about 3 miles (5 km) due south from Ballycastle. The Irish Grid reference is D115 364.

Geography

Knocklayd is the northernmost peak of the Antrim Hills, of conical shape with a height above sea level of 1686 ft (514 m) and a prominence of 1286 ft (392 m), and lies within the Antrim Coast and Glens AONB in which it is the third-highest summit. It is the second highest mountain in County Antrim after Trostan.[2]

A trig point has been erected on the summit.

Knocklayd is remarkable for the fact that ten townlands meet in a multipoint near its summit.[3] Clockwise from the north, these are Broom-More, Tavnaghboy, Kilrobert, Clare Mountain, Aghaleck, Corvally, Essan, Cleggan, Stroan, and Tullaghore.

Geology

Knocklayd consisty chiefly of Dalradian schists and gneisses and is covered by chalk and basalt.[4] A mica platform extends between Knocklayd and Tor Point over a distance of about 6 miles (10 km). Limestone overlay the slate and surrounds the mountain in a diameter of about 1 1/2 miles (2.5 km) and is itself covered by basalt. Quartz and chalcedony may be found on the mountain. [5]

Archaeology

Carn an Truagh ("Cairn of Woe" or "Cairn of Sorrow", also called "cairn of the three", as according to legend three Danish princesses are presumed to be buried there[6]) surrounds the summit. It is about 4 m high and 20 m in diameter[7] and a scheduled monument. The structure is almost certainly a passage tomb; it has never been excavated, but it is exposed in places through erosion.[8] It consists of white quartz and is covered by peat and grass.

Knocklayd is further surrounded by several standing stones.[9]
