Now I know that there are analogues of this in Lasnamäe too.
A room with high walls.
I love Soviet-era commieblock areas and buildings both in former USSR and in Eastern Europe. Highway ("Magistraal" in Estonian) takes me through such areas and some nice blocks are located right next to them. I am happy that I can enjoy these buildings and areas in my hometown Tallinn every day. (In case you wanted to see shopping mall Magistral in Mustamäe, please go to https://magistral.ee.)
