Marilyn

A Marilyn is any hill in Great Britain or Ireland with at least 150 m (492 ft) of relative height. There are 1555 Marilyns identified: 1215 in Scotland, 179 in England, 156 in Wales and 5 on the Isle of Man. There are another 453 in Ireland (including Northern Ireland).

The necessary relative height means that some well known hills and mountains are not included on the list, such as Bowfell, the Langdale Pikes and Glyder Fach, while other smaller and less popular ones are.
