 Water-power was first introduced to England by John Lombe at his silk mill in Derby in 1719, but it was Richard Arkwright who applied water-power to the process of producing cotton in the 1770s. His patent of a water frame allowed cotton to be spun continuously, meaning it could be produced by unskilled workers. Cromford Mill was the site of Arkwright's first mill, with nearby Cromford village significantly expanded for his then-new workforce; this system of production and workers' housing was copied throughout the valley. To ensure the presence of a labour force, it was necessary to construct housing for the mill workers. Thus, new settlements were established by mill owners around the mills – sometimes developing a pre-existing community – with their own amenities such as schools, chapels, and markets. Most of the housing still exists and is still in use. Along with the transport infrastructure form part of the site. A transport infrastructure was built to open new markets for the mills' produce.
