Grimma in the context of Central Germany (cultural area)

The Mulde (German pronunciation: [ˈmʊldə] ) is a river in Saxony and Saxony-Anhalt, Germany. It is a left tributary of the Elbe and is 124 kilometres (77 mi) long.

The river is formed by the confluence, near Colditz, of the Zwickauer Mulde (running through Zwickau) and the Freiberger Mulde (with Freiberg on its banks), both rising from the Ore Mountains. From here the river runs northwards through Saxony (Grimma, Wurzen, Eilenburg, Bad Düben) and Saxony-Anhalt (Jeßnitz and Dessau, the old capital of Anhalt). The Mulde flows into the Elbe 3 kilometres (2 mi) north of Dessau.

Colditz Castle (or Schloss Colditz in German) is a Renaissance castle in the town of Colditz near Leipzig, Dresden and Chemnitz in the state of Saxony in Germany. The castle is between the towns of Hartha and Grimma on a hill spur over the river Zwickauer Mulde, a tributary of the River Elbe. It had the first wildlife park in Germany when, during 1523, the castle park was converted into one of the largest menageries in Europe.

The castle gained international fame as the site of Oflag IV-C, a prisoner-of-war camp during World War II for "incorrigible" Allied officers who had repeatedly attempted to escape from other camps.
