Belgrade Fortress (Serbia)

The Belgrade Fortress, consists of the old citadel (Upper and Lower Town) and Kalemegdan Park (Large and Little Kalemegdan) on the confluence of the Sava and Danube rivers, in an urban area of modern Belgrade, Serbia. It is located in Belgrade's municipality of Stari Grad. Belgrade Fortress was declared a Monument of Culture of Exceptional Importance in 1979, and is protected by the Republic of Serbia. It is the most visited tourist attraction in Belgrade, with Skadarlija being the second. Since the admission is free, it is estimated that the total number of visitors (foreign, domestic, citizens of Belgrade) is over 2 million yearly.

Belgrade Fortress is generally divided into four sections. The four sections, two of which make the fortress itself (Donji and Gornji Grad) and two make Kalemegdan park today, were divided by the Tsarigrad Road, on the location of modern pedestrian path next to the Cvijeta Zuzorić Art Pavilion.
