The biggest European ongoing gentrification process has been occurring in Łódź from the beginning of the 2010s. Huge unemployment (24% in the 1990s) caused by the downfall of the garment industry created both economic and social problems. Moreover, vast majority of industrial and housing facilities had been constructed in the late 19th century and the renovation was neglected after WWII. Łódź authorities rebuilt the industrial district into the New City Center. This included re-purposing buildings including the former electrical power and heating station into the Łódź Fabryczna railway station and the EC1 Science Museum.
