Located at the confluence of the Danube and Sava Rivers, Belgrade is the capital city of the Republic of Serbia. The Belgrade metropolitan area has a population of 1.65 million (2011 census), which ranks it as one of the largest cities in southeastern Europe. Human occupation of the Belgrade area can be traced back over 6,000 years, and a city that became Belgrade existed by at least 279 BC. Throughout recorded history, the city has had many rulers and has suffered through numerous battles, frequently being completely destroyed and rebuilt in the process. In recent history, it was the capital of the socialist state of Yugoslavia for most of the 20th century.
The core of old Belgrade—known as Kalemegdan—is located along the right banks of both the Danube and the Sava Rivers (image center). To the west across the Sava, Novi Beograd (New Belgrade) was constructed following World War II. The difference in urban patterns between the older parts of Belgrade and Novi Beograd is striking in this astronaut photograph from the International Space Station. Novi Beograd has an open grid structure formed by large developments and buildings such as the Palace of Serbia—a large federal building constructed during the Yugoslav period, now used to house elements of the Serbian government. By contrast, the older urban fabric of Belgrade is characterized by a denser street grid and numerous smaller structures.
Other suburban and residential development (characterized by red rooftops) extends to the south, east, and across the Danube to the north. The location of Belgrade along trade and travel routes between the East and West contributed to both its historical success as a center of trade and its fate as a battleground. Today, the city is the financial center of Serbia, while Novi Beograd supports one of the largest business districts in southeastern Europe.
Astronaut photograph ISS034-E-61717 was acquired on March 5, 2013, with a Nikon D2Xs digital camera using an effective 700 millimeter lens, and is provided by the ISS Crew Earth Observations experiment and Image Science & Analysis Laboratory, Johnson Space Center. The image was taken by the Expedition 34 crew. It has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Caption by William L. Stefanov, Jacobs/ESCG at NASA-JSC.
Situated along key travel routes between the West and East, this capital city has been settled for at least 6,000 years and has changed rulers and layouts many times.
