That was definitely built by the Stalin architects. Stalin built his ridiculous “Palace of Culture and Science” abominations all over his empire. I have toured the one in Warsaw. They are nicknamed “Stalin’s cock.” Inside is identical to this photo except the one in Warsaw the wood floors are all rotten from water damage. Everything inside is ridiculous soviet art and architecture.
I was just there. As they say, the view from the top of Palace of Culture and Science is the best in Warsaw, because you don’t see The Palace of Culture and Science.
