If Marxism/Communism hadn’t proven to be an utter, abject failure economically, Soviet architects had some kicking projects planned. Stuff like the above. And this.

Of course, it was such a miserable flop at generating wealth, the Soviet’s built nothing but soulless concrete bunkers with all their good architecture having been built under the Czars.

See more of these amazing renderings of unbuilt Soviet buildings here, at the “Unrealised Moscow” site. Very, very cool.
