Beogradska Tvrdava (Belgrade Fortress) 
Description
Dominating the skyline above the point where the Danube and the Sava rivers join the fortress is one of the defining sights of the city. The area is part of a large park that is open 24/7 to wander round and take in the ruins of the walls and towers. Some parts of the fortifications have been converted into museums and exhibitions which do charge and keep standard hours.
