Budapest is Hungary’s capital and largest city, as well as one of the largest cities in the European Union. It serves as the country’s main political, cultural, economic, industrial, and transportation hub.
Budapest became a single city occupying both sides of the Danube on November 17, 1873, with the union of Buda and Buda on the west bank and Pest on the east bank.
The banks of the Danube, the Buda Castle Quarter, Andrássy Avenue, Heroes’ Square, and the Millennium Underground Railway, the world’s second-oldest metro line, are all part of Budapest’s enormous World Heritage Site. It is home to about 80 geothermal springs, the world’s biggest thermal water cave system, the world’s second largest synagogue, and the world’s third largest Parliament building.
