Berlin Observatory
The construction of the new Berlin Observatory proceeded from a cabinet order of 10 November 1830 according to the design of Schinkel. An approximately one hectare plot was acquired at a price of 15,000 Thalers in the present-day area of Berlin-Kreuzberg. The foundation stone was laid on 22 October 1832 and the observatory was ready by 1835, on the area currently bounded by the streets ″Friedrichstraße″, ″Besselstraße″ and ″Lindenstraße″. The southern end of the ″Charlottenstraße″ was later named ″Enckeplatz″ in honor of the director at that time and the observatory acquired the address of Enckeplatz 3 A (now: ″Enckestraße 11″).
Berlin Declaration (1945)
An Allied Control Council was established on 30 August 1945 to execute supreme governmental power over Allied-occupied Germany, which now did not include the German eastern territories. In its initial proceedings, the Allied Control Council assumed itself to be the sole repository of German state sovereignty especially in respect of external relations, but largely left each of the Allied Powers to administer their own occupation zones as they saw fit. The functioning of the Allied Control Council proved however, to be severely compromised by obstruction from one or another of the Allied Powers represented on it; initially France (who had not been invited to the Potsdam Conference and refused to be bound by the Potsdam Agreement), and latterly by the Soviet Union - who in 1948 walked out of the Control Council, preventing it from meeting again until 1991.
