Łódź

Łódź grew from eight hundred people in 1820 to over three hundred thousand by 1900 on cotton, with Polish, German, Jewish and Russian mill owners building palaces along Piotrkowska street — at five kilometres, one of the longest commercial streets in Europe. Izrael Poznański's factory complex is now a shopping and museum quarter, and the city's film school taught Polański, Wajda and Kieślowski.
