Lobau
Updated:
Lobau is part of the national park Donau-Auen, which is immediately east of Vienna. Wikipedia[a] has a short article about it, but the city's own site in German[b] is much better.
Some short points made in the German version:
-
The Lobau was originally an island in the Danube.
-
The Danube islands were very speices-rich environments, making the islands attractive for hunting.
-
When the Danube's flow was regulated Lobau ceased to be an island.
