Austrian culture is characterised by historical and modern influences, including a history of interaction primarily between Celtic, Roman, Slavic and Germanic peoples. Austria is particularly known for its classical music, folk music, baroque architecture, coffee culture, winter sports and Alpine traditions.

Lower Austria is one of the nine states of Austria, located in the northeastern corner of the country. Major cities are Amstetten, Krems an der Donau, Wiener Neustadt and Sankt Pölten, which has been the capital of Lower Austria since 1986, replacing Vienna, which became a separate state in 1921. With a land area of 19,186 km² (7,408 sq mi) and a population of 1.7 million people, Lower Austria is the largest and second-most-populous state in Austria.

Vienna is the capital, most populous city, and one of nine states of Austria. It is Austria's primate city, with just over two million inhabitants. Its larger metropolitan area has a population of nearly 2.9 million, representing nearly one-third of the country's population. Vienna is the cultural, economic, and political center of the country, the fifth-largest city by population in the European Union, and the most populous of the cities on the river Danube.
