 There is evidence, from flint finds, of occupation of a site, known as Westbury Sleight during the Mesolithic period, which fieldwork during 2007 suggested was a platform cairn with field banks of Bronze Age date.In 1969 traces of an infilled cave were discovered in a limestone quarry which produced numerous bones from extinct animals and flakes of flint and chert.Westbury-sub-Mendip was listed in the Domesday Book of 1086 as "Westberie", meaning 'The west hill under the Mendip Hills' from the Old English "west" and "beorg".
