The Wien is a river that flows through the city of Vienna. It gave the city its name. It is 34 kilometres long (21 miles), of which 15 km are within the city. Its drainage basin covers an area of 230 km² (89 mi²), both in the city and in the neighbouring Wienerwald. In German, the river is colloquially called the “Wienfluss”. Since English uses the name “Vienna” for what in German is called “Wien”, in English the river is sometimes called the “Vienna River”.
The Wien has its source in the western Wienerwald near Rekawinkel and its mouth at the eastern end of the city centre of Vienna, next to the Urania, where it flows into the Donaukanal (“Danube canal”), a branch of the Danube. That is what you can see on today’s picture, the bridge is going over the river before it runs out in the canal behind it. This is also the bridge that was featured in the film ‘Before Sunrise.’ 😉
Within the city limits, the river bed consists almost entirely of concrete, which was installed between 1895 and 1899 in order to stop the devastating floods, sometimes accompanied by cholera, which the river had regularly caused before that time. At the same time, the Stadtbahn (“city railway”) was built, which makes use of the concrete river bed and is only separated from the river by a wall. It is now part of the Vienna U-Bahn system. The river runs along the U4.
