Dessau-Roßlau
is an independent city (kreisfreie Stadt) and urban district in the German state of Saxony-Anhalt. It is situated at the confluence of the rivers Elbe and Mulde. The town was formed by merger of the independent city of Dessau with the town of Roßlau in the course of the "Kreisreform Sachsen-Anhalt" (Sachsen-Ahalt Regional Boundary Reforms) on 1 July 2007. The reform involved a reduction in the number of rural districts in Sachsen-Anhalt to 11 (from 21) and reflected an expected continuation of the significant population decline being experienced.
Dessau-Roßlau is the third largest town of Saxony-Anhalt by population, after Magdeburg and Halle.
