Derwent Valley Mills World Heritage Site

The Derwent Valley Mills were inscribed as a World Heritage Site on the World Heritage List in December 2001. The site is approximately 24km covers a number of industrial sites and settlements from Masson Mill at Cromford, in the north to Derby Silk Mill in the south. The Derwent Valley saw the beginning of the factory system, when new types of buildings were erected to use water power to house the new technology used for spinning cotton. In the Derwent Valley for the first time there was large-scale industrial production in a previously rural landscape. The need to provide housing and other facilities for workers and managers resulted in the creation of the first modern industrial settlements.
