Danube

n. one of the longest rivers in Europe

The Danube (In from earlier Danuvius, Celtic *dānu, meaning "to flow, run", ancient Greek Istros) is the longest river in the European Union and Europe's second longest river. It originates in the Black Forest in Germany as two smaller rivers — the Brigach and the Breg rivers—which join at the eponymously named German town Donaueschingen; it is from this point that it is known as the Danube. The river flows eastwards for a distance of some 2850 km (1771 miles), passing through several Central and Eastern European capitals, before emptying into the Black Sea via the Danube Delta in Romania and Ukraine.
