The vast Alexanderplatz has changed a little since I first visited it more than twenty years ago, but the change is superficial. Then, I’d started walking towards the TV tower (see the last photo below) from the Museuminsel, and reached a windblown square surrounded by grey concrete. My imagination was rife with Doblin’s book named after this square, and in comparison to that, the place looked colourless. I descended to the U-bahn station and left.

The gray concrete structures are now dressed in neon, and surrounded by young people doing exactly what they always do in Germany. On reunification, the property around Alexanderplatz remained in the hands of the East German company Treuhand. Kaufhof bought up GDR’s retail company Centrum-Warenhaus, and part of the deal was its property in Alexanderplatz. This is the building you see in the photo above. Redesigned by Paul Kleihues, it dominates the north-western corner of the plaza. We walked past the spray from the communist-era fountain to get to it, feeling too cold to take a photo. Diagonally opposite is a multistoried Saturn shop. I had forgotten my gorilla pod, and had marked this down as the place to buy one.

We walked past the clock showing time around the world to look at the buildings across the road. There was the Alexa, a large modern departmental store (featured photo). A little further down was the ministry of education (photo below), with its restored Walter Womacka mural from the time this area was still part of East Berlin. Next to this tower is the shallow dome of the Berlin conference center. Both were made by Hermann Henselmann. We turned back into the windy square. The storm was on us. A light rain had begun to fall. It was time to move on.

Alexanderplatz was built in the 19th century. By 1882 the S-bahn station had come into existence. You can see this as the horizontal tubular structure in the photo below. The U-bahn was built in 1913. The square has been reconceived thrice. Once in 1928, an architectural competition was held to build a new square for a metropolis. The de-facto winner was the influential architect Peter Behrens. Only two of his buildings were finished before the global crisis of the 1930s brought the development to a halt. Photos taken immediately after the was show that the two, Berolinahaus and Alexanderhaus (the buildings on the left edge of the featured photo), were heavily damaged during the war. They were reconstructed later.

Photos from that period also show that the S-bahn station was badly damaged. It seems that during the Battle of Berlin, a Soviet T-34 tank drove into the underground tunnel since it did not recognize the entrance to the train line in time. This may have given rise to rumours of Soviet tanks trying to outflank German defenders by driving through tunnels. The war damage was not repaired for a while. Then, in 1964, the DDR made everything over again, in the shape that you see it in now. In 1993 there was yet another architectural competition, and the winning design would replace everything here by ten high rises. These have not got off the ground yet.

For architectural sarcasm you could do worse than read this or this. A little search led me to an interesting article on the maze of unfinished construction below Alex.
