Derwent Valley Mills

The Derwent Valley Mills World Heritage Site stretches for 24 kilometres along the River Derwent in Derbyshire. It covers 12.3 square kilometres from Matlock Bath in the north to Derby city centre in the south. Within its boundaries lie mill complexes, workers’ housing, weirs on the river, and transport links built to serve the mills. The site includes the communities of Cromford, Belper, Milford, and Darley Abbey. Among its 838 listed buildings are 16 Grade I structures, 42 Grade II*, and 780 Grade II. Nine further structures are Scheduled Ancient Monuments. The valley saw the birth of the modern factory system in the 18th century. Richard Arkwright developed the water frame here, allowing cotton to be spun continuously by unskilled workers. His first mill at Cromford led to the expansion of nearby Cromford village for the workforce. Jedediah Strutt, Arkwright’s partner, built mills at Belper and Milford between 1776 and 1781. Thomas Evans established a mill at Darley Abbey in 1782. The industry declined in the early 19th century as Lancashire took over, but many buildings survive and some now house museums. Visitors walk through well-preserved mill complexes and workers’ housing that still stand today. The Cromford Canal and Cromford and High Peak Railway remain part of the landscape. A cycle-way runs the length of the World Heritage Site, linking the key locations. The buildings include mills, schools, chapels, and markets built for the mill communities. Some structures are open to the public, offering a view of the valley’s industrial past.
