Drone View of Vienna UN Island DonauInsel

Donauinsel, also known as the Danube Island, is a long, narrow artificial island located in Vienna, Austria. It was constructed between 1972 and 1988 to protect the city from flooding by separating the Danube River into two channels. The island is about 21 kilometers long and is primarily used as a recreational area.

The island has been developed into a popular space for outdoor activities, including cycling, swimming, and picnicking. It hosts the annual Donauinselfest, one of Europe’s largest open-air music festivals, attracting millions of visitors. The island also serves as a significant green space in Vienna, providing an area for leisure and contributing to the city’s efforts in urban sustainability.

The island is an example of how urban design can balance infrastructure needs, such as flood protection, with environmental and recreational functions.
