The textile mills in the Derwent Valley had a massive impact on world history. This was the birthplace of the modern factory, where the innovations of industrial pioneers, coupled with access to tireless water power, enabled mass production to occur for the first time. The communities created to support the early mills are remarkable, and much has survived of the early workers' housing in Cromford, Belper, Milford and Darley Abbey. Now inscribed on the UNESCO World Heritage List, the Derwent Valley Mills are beginning a new life, with restoration and fresh uses for historic buildings along the valley. In places, views have been lost and buildings demolished or changed, yet this historic valley is as fascinating now as it ever was. Using a selection of old and new images, this book highlights the progress being made and the work that still needs to be done, while celebrating the diversity and heritage of these mills and communities.
