The Kreuzberg is a hill in the Kreuzberg locality of Berlin, Germany, in former West Berlin. It rises about 66 m (217 ft) above the sea level. It was named by King Frederick William III of Prussia after the Iron Cross which crowns the top of the Prussian National Monument for the Liberation Wars, designed by Karl Friedrich Schinkel, on its inauguration on 30 March 1821.
