For some reason, I love pictures of nature overtaking man-made construction, like those in this Flickr gallery from Russia. For the same reason, I loved the book The World Without Us, which speculates how long it would take our man-made artifacts to be reclaimed by nature if we weren't there to maintain them.
This gallery from Sarajevo evokes much the same fascination, even though it's the exact opposite concept. It includes side-by-side pictures (like the one below), of buildings nearly destroyed in the Siege of Sarajevo (1992-1996) next to the same scene in 2011.
I'm not sure, but the building in the background looks like the Bosnian parliament building shown burning in the Wikipedia article about the war:
Hard to imagine such reconstruction was even possible. The other photos of the renewal in Sarajevo (at the link below) are equally powerful.
