Mourne Mountains

The Mourne Mountains are a compact range of granite peaks in County Down, rising from the Irish Sea coast to a high point of 850 metres at Slieve Donard, the highest summit in Northern Ireland. The range is contained by the Mourne Wall, a dry-stone boundary wall constructed in the early twentieth century, which traverses fifteen summits over roughly 35 kilometres. The wild character of the Mournes strongly influenced the landscape writing of C.S. Lewis in his childhood.
