Berlin Modernism Housing Estates is a World Heritage Site designated in 2008, comprising six subsidized-housing estates in Berlin, Germany. Dating mainly from the years of the Weimar Republic (1919–1933), when the city of Berlin was particularly progressive socially, politically and culturally, these buildings contributed to improving housing and living conditions for people with low incomes through innovative approaches to architecture and urban planning.
