The first event is the "Pride Serbia" Parade that will start at 11:00 a.m. on Saturday in Belgrade and is expected to end at 2:00 p.m. The parade will start at Pionirski Park and move to Republic Square. The official estimate of event participants is 200 to 300. This is not the larger "Belgrade Pride Parade", but a smaller event organized separately. The police will close the road for the parade.
The second event is a protest organized by the citizens' initiative "Let's Not Drown Belgrade" that will start at 6:00 p.m. on Saturday in front of Belgrade City Hall, Dragoslava Jovanovica #2. The organizers have stated that the protest is directed against the recent demolition of buildings in Savamala. After the protest, rally participants will walk through Belgrade. The route is not yet publicized, but is expected to end at the Palace of Serbia. The official estimate of event participants is 4,000 to 5,000.
Even demonstrations intended to be peaceful can turn confrontational and escalate into violence. You should avoid areas of demonstrations, and exercise caution if in the vicinity of any large gatherings, protests, or demonstrations.
