Concrete utopia of German Lebensraum In January 1943, the urban planning department in Litzmannstadt designed a new city centre for the German population, featuring streets for parading and a roll call square. This was superimposed onto a cadastral map of the Jewish ghetto. Although it was limited in its implementation, this 'concrete utopia' of German 'Lebensraum,' served as a catalyst for the Nazis to enact sweeping and severe measures against the Jewish residents.
