The Kreuzberg is a natural hill and forms part of the Tempelhofer Berge range (Tempelhof hills) stretching along the northern descent of the Teltow Plateau between Schöneberg and the Rollberge in Neukölln. It rises about above the sea level and above the northerly adjacent Berlin-Warsaw glacial valley. The Teltow Plateau is a flatly undulating ground moraine landscape. The Kreuzberg's relatively steep northern slope derives from the erosion by meltwater running into the Berlin-Warsaw glacial valley, when it was formed by the Weichselian glaciation. The Berlin-Warsaw glacial valley stretches to between the southern Kreuzberg and the northern Prenzlauer Berg, thus forming here the narrowest point between the northerly Barnim Plateau and southern Teltow Plateau.
