I agree about possibly nKorea. I did a short dig earlier today and was looking at photos of the “north korean ski resort”. Somewhat similar architecture.
Also looked at “nordic concrete architecture red door” and some other search terms.
Who posted? Who knows. Will dig on the chan in a bit.
#1 Pal, did you catch what bread that was on? Assuming 8Chan?
First thing I thought of when I saw those pics was the international seed vaults in the nordic.
