The Devonshire Dome building (previously known as the Devonshire Royal Hospital) 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 Buxton Campus of the University of Derby.
