The Danube is Europe's second-longest river, after the Volga and flows through Central and Eastern Europe.

The Danube was once a long-standing frontier of the Roman Empire and today flows through 10 countries.

The river runs through the largest number of countries in the world (the Nile is second with 9 countries). Originating in Germany, the Danube flows southeast for 2,850 km, passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries.
