Danube
Classified as an international waterway, it originates in the town of Donaueschingen, in the Black Forest of Germany, at the confluence of the rivers Brigach and Breg. The Danube then flows southeast for about , passing through four capital cities (Vienna, Bratislava, Budapest and Belgrade) before emptying into the Black Sea via the Danube Delta in Romania and Ukraine.
Source of the Danube
The Donaubach spring was considered the source of the Danube since the 15th century at least (Hartmann Schedel in his Weltchronik from 1493), but several hints suggest that this might have been true even in Roman times (Pliny the Elder in Naturalis Historia), in which the river was located in the fringes of the populated areas. The oldest cartographic depiction by Sebastian Münster from 1538 shows the Donaubach spring as a rectangular pool; in 1875, the spring was modelled into a round pool after Adolf Weinbrenner's design. In 1895 the artist Adolf Heer created a group of statues above the pool, depicting “the mother Baar” showing her "daughter", the young Danube, the way. The supposed source of the Danube is a popular tourist attraction, which is however closed until Autumn 2015 due to extensive renovation and restoration.
