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″).
Göttingen Observatory
In 1941, during World War II, Paul ten Bruggencate became the director of the Göttingen University Observatory. In pursuit of his interest in observing the Sun, he looked for a new solar telescope. With the help of the military, he was able to build a solar telescope near the already existing telescope at Hainberg. Unsatisfied with the cloudy weather conditions in Germany, ten Bruggencate established another solar observatory in Switzerland: the Locarno Observatory was planned and built in the late 1950s. It was closed in 1984 and the equipment was transferred to the Teide Observatory in Tenerife, Spain, where the University of Göttingen now shares the operation of several solar telescopes.
