Exhibition in Berlin's senate office of city planning. What you see here is a small view of a quite large model with the changes (shown in white) that the city already went through or will get through. Looks significant, doesn't it?
Another model of Berlin. The changes are in bright white. Like on the other pics you can see what will be done to the Alexanderplatz on the far right. Also of interest the area around the Berlin main station in the west (where the river makes a semi-circle) and the area around Leipziger Platz / Potsdamer Platz in the south.
