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″).
Vatican Observatory
In the 18th century, the Papacy actively supported astronomy, establishing the Observatory of the Roman College in 1774. In 1789–1787, the "Specola Vaticana" in the Tower of the Winds within the Vatican was established under the direction of Msgr. Filippo Luigi Gilii (1756–1821). When Msgr. Gilii died, the "Specola" was closed down because it was inconvenient for students in the city because the dome of St. Peter's obstructed its view. Its instruments were transferred to the College Observatory. A third facility, the Observatory of the Capitol, was operated from 1827 to 1870.
