Indeed. In fact inside the Reichstag during the restauration some old drawings by russian soldiers were found and preserved.
Unfortunately most cities of Germany were not rebuild nicely, one reason was that after the war many cities weren't rebuild according to the old plans, but rather according to new urban concepts like "car friendly cities" (Autogerechte Stadt). Many times those old houses not being destroyed in the war were destroyed after the war. Thus cities like Cologne, Hanover and Mannheim are not really beautiful today, and only recently it is tried to replace some of the cheap architecture of the 1950s with something more interesting.
Berlin is special, because it was rebuilt Soviet - Style in the East, Western Style in the west, and in fact a lot of old buidlings survived until the 1990s in order to be restored then. This makes the city very interesting.
I think sometimes we should acknowledge the hard work many people in Europe did in the years after the war in order to bring the European countries back to normality. Without the ERP programme of the US, it would have been much harder.
