Belper North Mill, also known as Strutt's North Mill in Belper, is one of the Derwent Valley Mills, given UNESCO World Heritage Status in 2001.
The mill is sited in Belper, a town in Derbyshire, England, roughly halfway between Derby and Matlock.
The original North Mill, completed in 1786 by Jedediah Strutt, was destroyed by fire in 1803. Its replacement was built in 1804 by his son, William Strutt, on the foundations of the old mill and is one of the oldest surviving examples of an iron-framed 'fire-proof' building in the world.
In 2015 a report by Amber Valley Borough Council said the North Mill were in need of repair as they had suffered "significant damage", and the council was said to be was considering a compulsory purchase order.
