Hm, I'm not good in history of architecture, but I think in Germany the 'pain' has begun after 1945 ... an still lives on. And it's getting worse: destroying old buildings instead of rebuilding them - the results are concrete, steel, glass facades. In my opinion modern architecture is boring and ugly (yes, I know there are exceptions ...)
I agree with opinion, that modern architecture is boring, but it was something innovative - with no ornaments, functionality, hygiene... and the buildings began to appear simple in form and content. unfortunately ... although nowadays this architecture is increasingly appreciated. what I love? I love secession, XIX/XX century.
