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″).

After test observations by Paul Guthnick in the summer of 1906 a new site was found on a hill in the eastern part of the Royal Park of Babelsberg. The ground was placed at the observatory's disposal by the crown free of charge. The costs of the new buildings and the new instruments amounted to 1.5 million Goldmark and could be covered by selling the landed property of the Berlin Observatory. The old observatory built by Schinkel was pulled down later. In June 1911 the construction of a new observatory began in Babelsberg and on 2 August 1913 the removal from Berlin to Babelsberg was complete.
