Belgrade is located in South-eastern Europe, on the Balkan Peninsula, at the crossroads of Eastern and Western Europe.
The city lies upon the Danube River, the aquatic route connecting the countries of Western and Middle Europe to the countries of the South-eastern and Eastern Europe. Its harbour is visited by ships from the Black Sea, and with the deployment of the Rhine-Main-Danube channel it found itself at the centre of the most important aquatic route in Europe: Northern Sea – Atlantic – Black Sea. Due to its position it was rightfully named “Gates of the Balkans” and the “Doors of Middle Europe”.
The coordinates of Belgrade are marked in the centre of the city (in Knez Mihailova Street): 44°49’14" of geographic latitude north, 20°27’44" of geographic longitude east and 116.75 m above sea level.
The area around Belgrade consists of two different environments: the Pannonian plain to the north and Šumadija to the south. The Kosmaj (628 m) and Avala (511 m) mountains are near Belgrade. The length of riverbanks is 200 km, with 16 river islands, the largest being Ada Ciganlija and the Great War Island.
