Eyam Moor is a plateau-topped hill between the villages of Eyam and Hathersage in Derbyshire, in the Peak District of England. The summit of Sir William Hill is 429 metres (1,407 ft) above sea level. It is unclear whom Sir William Hill is named after. Candidates include the four Dukes of Devonshire called Sir William Cavendish, Sir William Saville (Lord of the Manor of Eyam) and Sir William Bagshaw (High Sheriff for Derbyshire in 1805).
