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″).
Berlin Palace
In 1992 von Boddien co-founded with Kathleen King von Alvensleben, (an American architect who had married into a German noble family), what evolved to be the Berlin City Palace Sponsoring Association – which became the most influential lobby group. The Association accumulated plans that had been believed lost, and funded a research project at the Technical University of Berlin to measure surviving photos and drawings of the Palace to create precise architectural plans. In 1993, on the world's largest scaffolding assembly, it audaciously erected a "trompe-l'oeil" mockup of two frontages of the Stadtschloss facade on a 1:1 scale on plastic sheeting. Privately funded by donations and sponsorship this "coup de théâtre" stood for a year and half. Showing a vision of central Berlin lost for fifty years, and how the palace could provide the missing link to the historical ensemble of the Zeughaus, the Altes Museum, and the Berlin Cathedral, the spectacle brought the debate to a temporary climax in 1993/4. While opinion continued to remain divided, it succeeded in winning over many politicians and other key figures for the endeavour.
