List of tributaries of the Danube
The Danube is Europe's second-longest river. It starts in the Black Forest in Germany as two smaller rivers—the Brigach and the Breg—which join at Donaueschingen, and it is from here that it is known as the Danube, flowing generally eastwards for a distance of some , passing through several Central and Eastern European capitals, before emptying into the Black Sea via the Danube Delta in Romania.
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.
