I live just outside of Belper in Derbyshire and apart from Belper being the former home of Thornton's chocolates, Belper is famous for its mill.
The following is a passage from the website.
'Jedediah Strutt began building mills in Belper from 1776. The original North Mill was completed in 1786 but was destroyed by fire in 1803. Its replacement, the present mill, was built in 1804 on the earlier mills foundations by Jedediah's eldest son William Strutt and is one of the oldest surviving example of an industrialised iron framed 'fire-proof' building and is now recognised as one of the most important industrial buildings in the World, and as such, is a central point in the Derwent Valley Mills World Heritage Site.'
