Marilyn timeline

Alan Dawson

January 2016

A Marilyn is a hill of any height with a drop of 150 metres or more on all sides. The Marilyns in Britain and the Isle of Man were first listed in the book The Relative Hills of Britain (RHB) by Alan Dawson, published by Cicerone Press in April 1992. At that time there were 1542 Marilyns, which had increased to 1556 by the end of 2015. Details of subsequent changes have been published in a series of update sheets from 1995 to 2014. A summary of the changes since 1992 are set out below.
