Donauinselfest

The Donauinselfest (German for "Danube Island Festival") is a free open-air music festival which occurs annually at Donauinsel in Vienna, Austria. The festival is hosted by SPÖ Wien. It is the largest open-air music festival in the world, with around 3 million visitors over 3 days. Performances take place in the festival area which is 4.5 km long and consists of 11 different open-air stages in 16 tented areas around the island. Stages are added or removed depending on the performance lineup. Local bands, DJs, and many world-famous artists have performed at the festival since its beginning in 1984. According to numerous media reports, the Donauinselfest is among Europe's biggest open-air festivals with over 3 million visitors. To ensure the safety of visitors, "house rules" were introduced in 2007 and checkpoint controls were established to help control certain items (such as glass and liquor inside the festival perimeter). Food stands offer a variety of Austrian and international cuisine, including Thai, Greek, Italian, Hungarian cuisine, Indian, and Turkish. Although all concerts are free, financial experts estimate the event generates €40 million in city revenue due to increased tourism.
