The district, which is home to 10334 people (as of December 2019) is located 19km/12mi southwest of downtown Berlin and 157.5km/98mi north of Dresden. The district is known worldwide for the 1942 Wannsee Conference, during which the Nazi Party organized the continuation of the Holocaust.

The location of Berlin-Wannsee in Europe.
Most of the district is located on a large island, surrounded by the Wannsee itself to the north/northeast and the Havel River as well as a row of smaller lakes on the other 3 sides. On the southern edge the Griebnitzsee separates it from Babelsberg (home of Europe’s largest movie studio), forming the border to the neighboring federal state of Brandenburg.
