By late 1867 the Berlin-Görlitz line was complete and the route, which passed through the countryside of the Spreewald and the Lower Lusatia and the towns of Königs Wusterhausen, Lübben and Lübbenau, officially opened on 31 December 1867.
The towns Ziesar, Bad Belzig, Niemegk, Treuenbrietzen, Jüterbog, Baruth/Mark, Dahme/Mark, Wittenberg, Loburg, Möckern, and Zerbst, as well as the municipalities Wiesenburg (Mark) and Rabenstein/Fläming, are situated in or at the border of the Fläming Heath.
The Oder-Spree Canal links the Dahme, at nearby Schmöckwitz, with the Oder river, at Eisenhüttenstadt, thus providing a navigable connection between Köpenick and the Oder.
The Dahme flows into the Langer See from the Zeuthener See, at the south-east end of the lake by the Berlin suburb of Schmöckwitz.
Important towns beside Cottbus and the historic capitals Lübben and Luckau include Calau, Doberlug-Kirchhain, Finsterwalde, Forst, Guben/Gubin, Lauchhammer, Lübbenau, Senftenberg, Spremberg, Vetschau, and Żary in present-day Poland.
Some photographs show gardens in Berlin, and the surroundings areas of Schwielowsee, Potsdam, Werder, Dahme an der Dahme, Küstrin and Lübbenau.
On 31 January 1942 Spreewald was on her approach to Bordeaux in France when she was torpedoed by U-333, whose commander, Kapitänleutnant Peter-Erich Cremer, believed her to be a British ship.
Neighboring districts are (from the north clockwise) Dahme-Spreewald, Spree-Neiße, the districts Kamenz and Riesa-Großenhain in Saxony, and the district Elbe-Elster.
Otto Unverdorben (October 13, 1806 - November 28, 1873) was a German chemist and merchant who was born in Dahme/Marke.
Besides its natural connection to the River Dahme, the Oder-Spree Canal enters the lake on its eastern shore, whilst the Gosen Canal links the lake's northern end to the Dämeritzsee.
In the Spreewald the river passes through the towns of Lübbenau, Lübben and Leibsch.
