Where does the Danube river originate?
The Danube or Donau is Europe's second longest river, after the Volga. It originates in the town of Donaueschingen, in the Black Forest of Germany, at the confluence of the rivers Brigach and Breg. The Danube then flows southeast for about 2,730 km (1,700 mi), passing through four capital cities before emptying into the Black Sea via the Danube Delta in Romania and Ukraine.
