Buxton, a spa town in Derbyshire, is the highest market town in England, some 1,000 feet (300 m) above sea level. Buxton is close to the county boundaries of Cheshire to the west and Staffordshire to the south, on the edge of the Peak District National Park. The municipal borough merged in 1974 with places that included Glossop to form the local government district and borough of High Peak. The town population was 22,115 at the 2011 Census. Sights include Poole's Cavern, a limestone cavern, St Ann's Well, fed by a geothermal spring bottled by Buxton Mineral Water Company, and Georgian buildings round John Carr's restored Buxton Crescent, including Buxton Baths. Also notable is the Frank Matcham-designed Buxton Opera House, which holds music and theatre events. The Devonshire Campus of the University of Derby occupies historic premises in the town. It is twinned with Oignies, France, and Bad Nauheim, Germany.
