That was a cool video. I've spent a lot of time in Belgrade, and it truly does have some interesting facilities, including a few more that didn't meet capacity requirements to be included here.
the indoor pool is the place to be! You get two for the price of one lol. edit: I think my favourite is the Hala Sportova Ranko Zeravica Arena. Normally I don't like the 60s and 70s era architecture but I really like this one. Think its the windows.
at 1:32 it looks like the one guy near the right hand free throw line is trying to start a fight with the guy in blue. There are 5 players down near the basket at the right or walking towards it, while the other 5 are way down the other end. I can't imagine what the context is of this photo.
There is only one stadium in Belgrade people should visit, FC Red Star stadium (Rajko Mitić) where you can really feel the history, spirit of Serbia, to hear so many stories from the past and to be amazed. Other stadiums are worthless
