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″).
Stuttgart Observatory
To gather enough monetary funds for the construction of the Observatory at the site it still is today, even such famous guest speakers as Albert Einstein followed the invitation to give a speech about astronomy and donate the revenue to the Schwäbische Sternwarte e.V.. The construction of the observatory, designed by Wilhelm Jost, took place in 1921. Already in early January 1922 the association started operations at the new observatory. During World War II, all activities at the observatory were suspended, only to be resumed in September 1947.
