In the East, the GDR had shown with Stalinallee what fantastic architecture it was capable of building: workers' palaces! The West had to counter. In the Hansaviertel, a former upper middle-class district that had been almost completely destroyed during the war, houses were to be built for people with little money. But where the East looked back with socialist classicism, West Berlin invited the Who's Who of modernist architects. And they all came! Experience urban masterpieces by Le Corbusier, Oskar Niemeyer, Alvar Aalto, Walter Gropius, Wils Ebert, Egon Eiermann and Wassili Luckhardt. And enjoy an architectural landscape into which the Tiergarten forest seems to flow. An almost idyllic anti-urbanity in the middle of Berlin. We can only warmly recommend the Karl Marx tour as a coherent complement to this tour, because without the former Stalinallee, the Hansa Quarter would not exist in this form. After these tours you will understand why these two quarters, these "two sides of the same coin", will soon be UNESCO World Heritage Sites...
