These are cheap proletarian flats built soon after WW2. The bronze plague in the corner of the building contains seething about the civil war which was lost by the Reds. It's literally commie-tier. Still they could afford beauty and ornaments, and today this area is very very bourgeois and inhabited by bohemian green middle class and the proletariat is banished to commieblocks. It's sad. Modernism punishes mostly the weakest ones, those who don't have money to escape the horrible modernist cityscape.
