The capital of Austria is also one of the nine federal states and, with around 1.9 million inhabitants, the most populous and, at 415 square kilometres, the largest city in the country. Until 1986, Wien was also the capital of Lower Austria, the largest province in the east, when it was replaced by St. Pölten. The Danube flows through the city from north to south-east over a length of more than 20 kilometres. With over 600 hectares of vineyards, Wien is the city with the largest wine production worldwide.
Viennese viticulture has a two-and-a-half-thousand-year history and is at least as old as the city itself when it was still a small settlement. Even the Celts and before them the Illyrians had practised viticulture in this area, which they called "Vedunia", in 500 BC, even before the Romans, as many finds such as wine barrels, pressing devices and grape seeds prove. Among others, also at the two vineyards Bisamberg and Nußberg, where many vineyards are still planted today. When Emperor Marcus Aurelius Probus (232-282) lifted the ban imposed by Emperor Domitian (51-96) on planting vines outside Italy, the legionaries in "Vindobona" began to cultivate vines and apply Roman methods. Today's large city with an area of over 400 km² is literally built on vineyards.
