About Derby

Derby is a unitary authority and city in the East Midlands of England, situated on the River Derwent at the southern edge of the Peak District. With a population of approximately 261,000 (2021 Census), Derby is a major industrial and manufacturing city with a unique claim to be one of the birthplaces of the Industrial Revolution. History and Heritage: Cradle of Industry Derby holds a remarkable dual distinction in the story of industrialisation. In 1721, the Lombe brothers — Thomas and John — completed what is believed to be the world's first successful water-powered silk mill in Derby, operated by water wheels on the River Derwent. Lombe's Mill employed over 300 workers using machinery modelled on Italian designs and represented the first large-scale use of mechanised production in a factory setting — making Derby a strong claimant to the title of birthplace of the factory system. The building is now home to the Silk Mill Museum, also known as the Museum of Making, which received a major renovation and reopened in 2021 as a hands-on celebration of manufacturing heritage. The broader Derwent Valley, of which Derby is the southern gateway, was designated a UNESCO World Heritage Site in 2001 specifically for its role as the cradle of the factory system. The valley contains a remarkable chain of early mills, mill workers' settlements, and associated infrastructure that documents the origins of modern manufacturing. Joseph Wright of Derby (1734–1797) is one of Britain's most celebrated 18th-century painters. His extraordinary series of "candlelit" paintings depicting scientific experiments and industrial processes — including "An Experiment on a Bird in the Air Pump" and "A Philosopher Lecturing on the Orrery" — capture the spirit of the Enlightenment and the Industrial Revolution with unique artistic power. The Derby Museum and Art Gallery holds the finest public collection of his work. In the 20th century, Derby became globally famous above all for Rolls-Royce. The company, founded by Charles Rolls and Henry Royce in 1906, established its manufacturing headquarters in Derby and has remained there ever since. Today, Rolls-Royce's Derby site is the global centre for the design, development, and manufacture of advanced aerospace engines, powering wide-body aircraft including the Boeing 787, Airbus A380, and many others. With approximately 12,000 employees at the Derby site, Rolls-Royce is the city's single largest private employer and one of the most important advanced engineering employers in the UK. Railway Manufacturing Derby has also been central to British railway manufacturing. The Derby Locomotive Works, opened by the Midland Railway in 1840, was for over 150 years one of the most important railway engineering centres in the world, building thousands of locomotives and carriages. The works — later operated by British Rail, Bombardier, and Alstom — continue to build and maintain rolling stock, most recently the Hitachi-designed Avanti trains for the West Coast Main Line. Toyota Manufacturing UK Adjacent to Derby at Burnaston, Toyota Manufacturing UK operates one of the most productive car manufacturing plants in Europe. Opened in 1992, the plant produces Corolla and Auris models primarily for export across Europe. With approximately 2,500 employees and supplier dependencies involving tens of thousands more, the plant is critical to the regional economy. Geography Derby covers approximately 78 square kilometres in the Derwent valley, with the city occupying flat valley land and rising to suburban hills to the north and east. The Peak District National Park lies immediately to the northwest. Kedleston Hall (National Trust), a magnificent neoclassical mansion by Robert Adam completed in 1797 and set in a vast deer park at the city boundary, is one of the finest country houses in England. Population and Demographics The 2021 Census recorded 261,000 residents. Derby is one of the more ethnically diverse cities in the East Midlands, with approximately 25% of residents from non-White-British backgrounds, including significant South Asian, Black, and mixed-heritage communities.
