• Slieve Donard from Irish: Sliabh Dónairt, meaning “Dónairt’s mountain” is the highest mountain in Northern Ireland and the wider province of Ulster, with a height of 850 metres (2,790 ft). One of the Mourne Mountains, it is near the town of Newcastle on the eastern coast of County Down, overlooking the Irish Sea. It is also the 7th highest peak on the island of Ireland. The Mourne Wall, built in the early 20th century runs up the western and southern slopes of the mountain, joining a small stone tower at the summit. Also on the summit are the remains of two ancient burial cairns, one of which is the remains of the highest known passage tomb in Ireland. In Irish mythology the mountain was associated with the mythical figures Boirche and Slángha.
