West-Berlin`s most important recreation area ...

The Wannsee is both a locality in the southwestern Berlin borough of Steglitz-Zehlendorf, in Germany, and a linked pair of lakes adjoining the locality. Both lakes, the larger Großer Wannsee (greater Wannsee) and the Kleiner Wannsee (little Wannsee), are located on the river Havel and are separated only by the Wannsee bridge. The larger of the two lakes covers an area of 2.7km² and has a maximum depth of 9m.
