As I was doing site-scouting for a future event in Skopje (thank you Culture Moves grant!), I also got a glimpse of the city's architecture in general.
There was a major earthquake in 1963, which destroyed a great deal of the buildings, which means that 60's and 70's flavour is prominent in the cityscape (even some newer buildings, I think). Also, brutalism. None of which is used for luring tourists, which I wonder.
