Quote - One associates socialist architecture with either impossibly heavy neoclassic buildings like the proposed Palace of Soviets of Moscow or drab parallelepipeds but it was not always that way: e.g. see the Tbilisi Roads Ministry Building or the Friendship Sanitorium in Yalta. The shape of the second building is so strange that CIA (having only access to satellite photos) kept considering it some kind of secret military installation.

Or of course, the Glorious Peoples Republic of the North Pole, as scene in that fine documentary of Socialist Life "Polar Express".
