Belgrade Fortress
Ancient fortifications overlooking the confluence of the Sava and Danube rivers are now one of Belgrade's prettiest city parks. The fortress was built, expanded, destroyed, and built again between the 1st and the 18th century, but current fortifications date largely to the Ottoman period in the 18th century. It's split into the Upper Town (Despot’s Gate, the Clock Tower, the Roman Well, and the Statue of the Victor), and Lower Town (Nebojša Tower, the Turkish bath, and the Gate of Charles VI). The lovely Kalemegdan Park surrounds it all. With spectacular views of the city and perfect sunsets over the rivers, this is one of the most romantic spots it the city. Kids will love the military museum's enormous collection of cannons and tanks, as well as the Grand Stairway, the zoo, and the children’s park. There are a few cafés and restaurants if you need a break. Some attractions charge a nominal fee.
