Hello! 😊
It's like burying something what was alive (the city), and keeping it alive in this way. It's a strange concept, but it works.
I agree, I also thought of Soviet architecture - I think it's the concrete that makes us feel like this.
You should absolutely go to Italy as there are so many beautiful places to see. We try to go every year, but there is still so much to see. If you go there don't forget to visit Florence or Sienna - those are my favorite place. And Sardinia of course 😊
Thank you for your thoughtful comment!
