the largest collection of bobbins in the world. Leawood Pumphouse is now a working museum which still does the original job of pumping water from the Derwent to Cromford Canal, Open on selected weekends. At Belper, while much of the site has been converted to other business uses, the Belper North Mill building houses the Derwent Valley Visitor Centre. This features displays of machinery and other items associated with the history of the Derwent Valley textile industry. At the extreme southern end of the site, Lombe's Silk Mill now houses the Derby Industrial Museum. This museum closed on 3 April 2011 and was mothballed for over two years. In October 2013 a programme started to reinvent the silk mill for the 21st Century, incorporating the principles of STEAM (Science, Technology, Engineering, Art and Maths). The museum now opens 4 days a week. The Derby Industrial Museum was re-branded as the Museum of Making in November 2021. It houses a series of exhibits about the history of the Derwent Valley Mills and the wider context of manufacturing.
