Das Allgäu is a region in the German South. It covers the south of Bavarian Swabia and southeastern Baden-Württemberg (plus parts of Austria). The region stretches from the pre-alpine lands up to the Alps. The main rivers flowing through are the Lech and Iller. The region is sub-divided into:
Das Oberallgäu (in Bavarian Swabia, in the state of Bavaria) Das Unterallgäu (in Bavarian Swabia, in the state of Bavaria) Das Ostallgäu (in Bavarian Swabia, in the state of Bavaria) Das Westallgäu (mainly in Upper Swabia in the state of Baden-Württemberg, but also a very small part in Bavaria)
The western Austrian part is the Kleinwalsertal in Vorarlberg, accessible from Germany only. The region is noted for its beautiful landscapes and is popular for vacations and therapeutic stays. It’s well known for its farm products, esp. dairy including Hirtenkäse (“herdsman’s cheese”) and Bergkäse (“hill cheese”). Besides tourism and dairy, another important economic sector is the building of industrial equipment and machinery, such as Fendt tractors. The alpine regions of the Allgäu rise to 2,000 m in altitude and are popular for winter skiing. The famous Neuschwanstein castle is located here. Famous people from the region include Ludwig Ganghofer (writer of Bavarian homeland novels), Max Ritter von Mulzer (WW1 pilot), Ernst Walter Mayr (leading evolutionary biologists of the 20th century), Klaus Nomi (countertenor & one of the first prominent German victims of HIV/AIDS), and Mario Götze (football player & scorer of the goal that made Germany the 2014 FIFA World Champions).
