The 10. Postcard from Tina's collection from today's (28.06.2012) post.
Potsdam is the capital city of the German federal state of Brandenburg and part of the Berlin/Brandenburg Metropolitan Region. It is situated on the River Havel, 24 km (15 mi) southwest of Berlin city centre.
The name "Potsdam" originally seems to have been "Poztupimi" from a West Slavonic name meaning "beneath the oaks", highlighting the area's many grand oak trees.
Potsdam has several claims to national and international notability. In Germany, it had the status Windsor has in Britain: it was the residence of the Prussian kings and German Kaisers, until 1918. Around the city there are a series of interconnected lakes and unique cultural landmarks, in particular the parks and palaces of Sanssouci, the largest World Heritage Site in Germany. The Potsdam Conference, the major post-World War II conference between the victorious Allies, was held at another palace in the area, the Cecilienhof.
