An area that's becoming increasingly interesting to explore is the Leipziger Baumwollspinnerei, the Leipzig Cotton Mill, in the district of Lindenau. 

This 10-hectare former industrial site was an important commercial center focusing on the cotton trade. 

At its peak before WWI, the complex formed a complete community that included 20 factories, homes, schools, and parks, along with more than 240,000 spindles.
