I had the luck of visiting post-soviet countries in Eastern Europe, and I can say I was somewhat admired by the block buildings that they have. Rows and rows of massive constructions that look alike, we even visited some apartments, and they had the same room placement, some had really old chandeliers, which gave a strange sense of luxury in a room that's really plain and simple. I think we visited the district where Chernobyl was filmed, but right now I can't remember the exact country.
