The first "Oranienbaum Summer School" took place in 2011 and was succeeded by another one in 2012, following the first conservation initiative at Schloß Oranienbaum, which was the "Oranienbaum Colloquium" for PhD Candidates in Conservation in 2008, the later Ulrich Schießl PhD-Colloquium.
Both Oranienbaum Summer Schools were organised by Claudia Hörster, Keeper of the Art Collection at the Royal Archives in The Hague, and Dr Wolfgang Savelsberg, Head of the Department of Palaces / Collections Kulturstiftung Dessau Wörlitz. The schools each lasted for four to five weeks, and both Dutch and German students participated. Besides the UvA Conservation Department, the Wall Paintings Departments of FH Potsdam, ABK Stuttgart and HfbK Dresden participated.
In 2011 the ‘Chambre in Chinoiserie Style’ was treated and in 2012 the ‘Anti-Chambre’, also a Chinoiserie.
