It's interesting how Communist architecture was so horrible, considering that its imagery was actually quite interesting (i.e. posters, etc.).
Even in ex-Communist Central and Eastern Europe, only (some of) the historical centers survived the dreadful invasion of the panel blocks. Still, most of the outskirts are incredibly depression. French banlieus also have their origin in this bizarre vision of what a community should look like.
I've seen small villages, that as far as I could see, only had apartment blocks. In the middle of an empty plain, the first line of construction was a circle of blocks with 15 floors. In the middle of the blocks, was normal looking town square with shops and the town hall. To one of the sides of this circles was the factory where almost everybody worked in.
It's interesting how Soviet Communism unwillingly replicated some of the worst traits of the industrial revolution. You just lived for the work you did in the factory.
it's a classical case of "what where they thinking". that's one of the problems with communism: they have no touch with reality. some communist state might draft the next five year plan consisting of shoes and three legged chairs while those dumbasses made that abomination without justifying it economically. well, at least kim jong il's greatness shall endure for over a millenia and show them capitalist dogs what north-Korean genius is capable of.
