General Information
Vienna is Austria’s capital and its largest city. It has a population of about 1.8 million people and is the tenth largest city in terms of population in the European Union. In 2015 Vienna was selected for the seventh time by the "Mercer" Foundation as the best city in the world in terms of levels of quality of life. Vienna is a green city, where green space occupies more than half of the metropolitan area.
Vienna is famous for being the world’s center of education, literature, music and science. After the collapse of the Austro-Hungarian Empire after World War I in 1918, Vienna lost much of its importance. After the end of World War II in 1945 it has become a global center for conferences and multi-center international agencies. Vienna is host to many major international organizations such as the United Nations and OPEC.
