The Danube flows through many cities, including four national capitals (shown below in bold), more than any other river in the world. Ordered from the source to the mouth they are:
The Danube is navigable by ocean ships from the Black Sea to Brăila in Romania and by river ships to Kelheim, Bavaria, Germany; smaller craft can navigate further upstream to Ulm, Württemberg, Germany. About 60 of its tributaries are also navigable.
Danube Promenade
The Danube Promenade () is located on the Pest side of Budapest, Hungary. On the bank of the Danube, this promenade extends from the Széchenyi Chain Bridge to the Erzsébet Bridge.
A row of hotels on the bank of the Danube began to be built in 1867: these were the Hungaria (1867 A. Skalinczky), Bristol, Carlton, and Ritz (Danube Palace). In 1945 at the end of World War II, only the Bristol (Danube Hotel) survived the destruction of the row of hotels on the bank of the Danube. In 1969 the final form of the Bristol Hotel was demolished.
