Vienna

Vienna is the largest city in Austria, with an estimated population of 4,284,379 as of 2006.

Vienna traces its history back to before the time of Christ. The first settlement in the area was founded by Celtic tribes at approximately 500 BC. Later, when the Romans conquered the area, it became the Roman city of "Vindobona". During the Middle Ages, the city became a center of Babenberg and then Habsburg power - and it was outside the city that Ottoman invasions of Europe were stopped in 1529 and 1683. Since 1805, except for the when Nazi Germany annexed Austria (German: Anschluss Österreichs), Vienna has been the capital of successive Austrian states: the Austrian Empire, Austria-Hungary, and then Austria.

Today Vienna is also an important center for international organizations and institutions. There are many United Nations offices in the city, and the United Nations Industrial Development Organization (UNIDO) is based in Vienna, as are the International Atomic Energy Agency (IAEA), the Organization of Petroleum Exporting Countries (OPEC), the Organization for Security and Co-operation in Europe (OSCE), and the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO).
