The Danube River flows through Budapest, Hungary’s capital.
Budapest developed on both banks of the Danube, with Buda and Óbuda on the western side and Pest on the eastern side. These settlements were united into one city in 1873. The river remains one of Budapest’s defining geographic features, crossed by landmark bridges including the Chain Bridge.
The Danube is Europe’s second-longest river after the Volga. It rises in Germany’s Black Forest and runs through or along the borders of ten countries before reaching the Black Sea through the Danube Delta. No other river passes through as many countries.
In Budapest, the river has shaped transport, trade, urban growth, and architecture. Several central sites, including the Hungarian Parliament Building and Buda Castle, stand beside or above the river. The Budapest section is also recognized within the UNESCO World Heritage listing for the Danube panorama and the Buda Castle Quarter.
The Rhine and Seine are important European rivers, but the Rhine does not flow through Budapest, while the Seine is associated with Paris. The Volga is Europe’s longest river and lies much farther east.
