Marilyn (hill)

This is a list of Marilyn hills and mountains in the United Kingdom, Ireland and surrounding islands and sea stacks. Marilyns are defined as peaks with a prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Munros). Thus, Marilyns can be mountains, with a height above , or relatively small hills. there were 2,010 recorded Marilyns.

Definition

The Marilyn classification was created by Alan Dawson in his 1992 book ''The Relative Hills of Britain''. The name Marilyn was coined by Dawson as a punning contrast to the ''Munro'' classification of Scottish mountains above , but which has no explicit prominence threshold, being homophonous with (Marilyn) ''Monroe''. The list of Marilyns was extended to Ireland by Clem Clements.

Marilyn was the first of several subsequent British Isles classifications that rely solely on prominence, including the P600s, the HuMPs, and the TuMPs. Topographic prominence is more difficult to estimate than topographic elevation, requiring surveys of each contour line around a peak, and therefore lists using prominence are subject to revision.

Although many of the islands' largest mountains, including Ben Nevis, Carrauntoohil, Scafell Pike and Snowdon, are Marilyns, many other large peaks such as Cairn Gorm, a number of Munros, and well-known hills such as Bowfell, the Langdale Pikes and Carnedd Dafydd, are not Marilyns because they do not have sufficient height relative to the surrounding terrain (i.e. they have taller "parents"). Not all Marilyns are even hills in the usual sense: Crowborough () sits in a town in East Sussex, whilst Bishop Wilton Wold highest point of the Yorkshire Wolds () lies alongside the A166 road. At the other extreme are Stac Lee () and Stac an Armin (), the two highest sea stacks in the British Isles, in the St Kilda archipelago, west of the Scottish mainland.

, there were 2,010 Marilyns in the British Isles, with 1,218 Marilyns in Scotland, including 202 of the 282 Scottish Munros; Munros with a Marilyn–prominence are sometimes called ''Real Munros''. There were a further 454 Marilyns in Ireland, 174 in England, 159 in Wales, and 5 in the Isle of Man. On 13 October 2014 Rob Woodall and Eddie Dealtry became the first people to climb all 1,557 Marilyns in Great Britain. , 11 ''Marilynists'' had climbed "all hills f Great Britainthat were classed as Marilyns at the time they recorded finishing the list" while, , 275 had entered the ''Marilyn Hall of Fame'' by climbing over 600 Marilyns.

By height and prominence

This list was downloaded from the ''Database of British and Irish Hills'' ("DoBIH") in October 2018, and are peaks the DoBIH marks as Marilyns ("M"). As topological prominence is complex to measure, these tables are subject to revision over time, and should not be amended or updated unless the entire DoBIH data is re-downloaded. The tables are structured to show rankings by height and prominence over the entire British Isles, or by region.

Updates

Since the table was downloaded, the following changes have been made to the list of recognised Marilyns:
*Added: Rhinog Fach, Wales, August 2021 (, prominence )
*Removed: Cheriton Hill, Kent (, prominence )
*Removed: Giur-bheinn, Islay (, prominence )

DoBIH codes

The DoBIH uses the following codes for the various classifications of mountains and hills in the British Isles, which many of the above peaks also fall into:
