The Berlin Modernism Housing Estates were designated a World Heritage Site in 2008, but, over a decade later, they are unknown to most visitors to Berlin. You shouldn\'t miss these remarkable examples of new urban and architectural typologies. On our tour we will visit three of the six estates, which were designed by famous architects like Walter Gropius (founder of the \"Bauhaus\"), Mies van der Rohe and Hans Scharoun. As an historian, book author and experienced guide, I can give you unique insights: You will not only learn about the technical and aesthetic concepts of this architecture, but I will also talk on the social and political background of these buildings. We will cycle mostly through quite side streets and parks, and you get to know Berlin off the beaten track. In addition to the beautifully restored houses dating from the years of the Weimar Republic, when the city of Berlin was particularly progressive, you will explore with me the rougher side of the German capital in its old working-class neighbarhoods.
