I know the place. Never been inside, but the fair is just across the street and I've been there a lot. The roof is quite interesting, I've seen several guys getting there and making very interesting photos.

Most of Belgrade, and many other cities here (but not as much) has acquired the ugly dark gray patina from a century of coal heating, plus the industry. This building would be quite nice if its façade was bright, or at least pressure washed, which never happened. In smaller cities they are renovating those old buildings more diligently, because it's the cheapest of all the things a local government can do, easy to skim off a percentage, and it's downtown where every (voter) person can see it. Belgrade has this trouble that it has too many of those buildings and too many politicians competing for what little money there is, so many of them never get touched by as much as a broom.

In my city, they have rebuilt the main street's pavement four times in the last 50 years, while some of the tributary streets still have the cobblestones from XIX century. I've seen this repeat in practically every city in Serbia I managed to visit this decade - and, then, also in downtown Sofia, only worse.
