Pleiße

The Pleiße (German pronunciation: [ˈplaɪsə] ) is a river of Saxony and Thuringia, Germany. It flows from south to north into the White Elster in Leipzig. Originally, its natural length was 115 km (71 mi); however, south of Leipzig, it has been straightened, which shortened it to around 90 km (56 mi).
The river is well accessible via the Pleiße cycle path.
The name Pleiße is of old Sorbian origin and means: "the swamp-forming water". It gave its name to the Pleissnerland (Plisni) on its lower reaches, which was important in the Middle Ages.
