Belgrade is situated in South-Eastern Europe, on the Balkan Peninsula. It lies at the point where the river Sava merges into the Danube, on the slope between two alluvial planes. The river waters surround it from three sides, and that is why since ancient times it has been the guardian of river passages. Because of its position it was properly called "the gate" of the Balkans, and "the door" to Central Europe. Along the ridge of the slope, from Kalemegdan, along the Knez Mihailova street, across Terazije to Slavija, stretches the main city traffic artery.
At Knez Mihailova street, the coordinates of Belgrade are marked:
- 44049'14" of northern latitude
- 20027'44" of eastern longitude
- altitude 116,75 m.
Belgrade is the intersection of the roads of Eastern and Western Europe which lead through the Morava-Vardar valley and Nišava-Marica valley to the shores of the Aegean Sea, to Asia Minor and to the Middle East. Belgrade lies on the Danube river, the sailing route, which connects the Western Europe and Central Europe countries with the countries of South-Eastern and Eastern Europe. By the construction of the artificial lake and the Đerdap power station, Belgrade became a river and sea port. The ships from the Black Sea sail to its docks, and with opening of the Rhine-Main-Danube canal, Belgrade came to the center of the most important sailing route in Europe: The North Sea - Atlantic - Black Sea route.
