The Lobau is a Vienna floodplain on the northern side of the Danube and partly in Großenzersdorf, Lower Austria. It has been part of the Danube-Auen National Park since 1996 and has been a protected area since 1978. It is used as a recreational area and is known as a site of nudism. There is also an oil harbour, and the Austrian Army uses the Lobau as a training ground. In addition to the water coming from the Alps through the Wiener Hochquellenwasserleitung, the Lobau is a source of groundwater for Vienna.

Löbau (Upper Sorbian: Lubij) is a city in the east of Saxony, Germany, in the traditional region of Upper Lusatia. It is situated between the slopes of the Löbauer Berg and the fertile hilly area of the Upper Lusatian Mountains. It is the gateway to this volcanic mountainous area and half way between the cities of Bautzen, Görlitz and Zittau.
