Nice pictures here. I visited Niš last summer (I have two friends there), and visited block-areas too. Nice blocks, but what was even more notable was that the rest of the architecture is also fantastic! One of my friends there has shown me many photos from Niš and almost every such photo tour contained some jawdropping architecture of single houses. That place with tall grey-yellow houses was my favourite too
There's a whole wall of that and hills and mountains in the background! How cool is that!
