Welsh Marilyns

A Marilyn is a mountain or hill in the United Kingdom, Republic of Ireland or Isle of Man with a relative height of at least 150 metres (492 ft), regardless of absolute height or other merit. The name was coined as a punning contrast to the designation Munro, used of a Scottish mountain with a height of more than 3,000 feet (914.4 m), which is homophonous with (Marilyn) Monroe.

There are 2,009 Marilyns identified: 1,216 in Scotland, 455 in Ireland (of which 66 are in Northern Ireland), 176 in England, 157 in Wales, 5 on the Isle of Man. Black Mountain, in the Black Mountains, on the border between England and Wales, was formerly counted in both countries but is now treated as being in Wales only. The list of Marilyns in Britain was compiled by Alan Dawson in his book The Relative Hills of Britain, and continues to change as resurveying produces revised heights for hills and the passes between them. The list was extended into Ireland by Clem Clements in a booklet, The Hewitts and Marilyns of Ireland.
