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″).
Public Observatory Regensburg
The precursor of the currently existing observatory was founded in 1774 at the Saint Emmeram's Abbey. Prince-Abbot Frobenius Forster dedicated two towers of the abbey which were prepared for astronomical and meteorological observations in the years 1774 and 1775. When the abbey was dissolved in 1812, the observatory was moved into a tower in the city wall. This tower was named "Placidustower" after Placidus Heinrich, one of its first users and a monk of the Order of Saint Benedict. Placidus Heinrich introduced astronomy as a subject at the Lyzeum in Regensburg, a university dedicated to Philosophy and Theology. The remaining instruments are now part of the historical collection at the University of Regensburg.
