The Silk Mill, Derby.

Now the Derby Industrial Museum.

The original Silk Mill was built between 1717 and 1721 and was Britain's first mill.
It was five storeys high and was powered by a water wheel which drove all the wooden machinery
(several storeys high) within the building by wooden shafts and cogs.
When in operation it was a regarded as a wonder of the age and attracted many visitors,
including Daniel Defoe and Boswell.

The Derwent Valley, from here to Cromford, is designated a World Heritage Site.
