The Devonshire Royal Hospital building (now popularly known as the Devonshire Dome) is a Grade II* listed 18th-century former stable block in Buxton, Derbyshire. It was built by John Carr of York and extended by architect Robert Rippon Duke, who added what was then the world's largest unsupported dome, with a diameter of 44.2 metres (145 ft). It is now the site of the Devonshire campus of the University of Derby.
