Danube
The Danube is the second-longest river in Europe, stretching approximately 2,850 kilometers, and is unique for being the only major European river to flow from west to east. It originates in the Black Forest of Germany and empties into the Black Sea through the vast Danube Delta in Romania and Ukraine. Along its course, the river flows through or borders ten countries and connects four national capitals: Vienna, Bratislava, Budapest, and Belgrade. Historically, the Danube served as a vital trade route and a natural northern frontier of the Roman Empire, known as the Limes. Today, it remains economically crucial for inland shipping, hydroelectric power generation, and providing drinking water to millions of people. The Danube Delta is a UNESCO World Heritage site and represents one of the most biodiverse ecosystems in the world. Despite environmental challenges, the Danube continues to be a central artery for European cultural and economic integration.
