At the Brigittenauer Sporn ("Brigittenau Spur"). This is where the Donaukanal, a canalised branch of the Danube, leaves the main river. After 17.3 kilometres, it flows back into the main river, forming a nameless island that is shared by two Viennese districts: Leopoldstadt, the 2nd district (19.24 km², 110,100 inhabitants) and Brigittenau (5.67 km², 86,930 inhabitants).
On the right you can see the administrative building of the Nussdorf weir by Otto Wagner, which can't be seen in the picture. The point of view is in Nussdorf, a neighbourhood of Döbling, the 19th district.
On the left you can see the Donauturm and the high-rises of the Donau City.
All these places are a short bike ride away from my home.
