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″).
Belgrade Observatory
Nedeljković was appointed first director of the newly founded Observatory. On 1 July 1887 Nedeljković started his activity at the provisory astronomical and meteorological observatory which was located in the rented house of the Gajzler family at 66 "Svetozara Markovića" Street. Located at the crossroads of the "Vojvode Milenka" and "Svetozara Markovića" streets in the historical neighborhood of Vračar (though today administratively in the municipality of Savski Venac), the house still stands today. Adopting the justified request of Prof. Nedeljković, a new Minister of Education, Dr Vladan Đorđević passed on 27 September 1888 the Regulation on the establishment of unified network of meteorological stations in the whole country. Then Observatory become Central meteorological station for data collection.
