Integrated into the wood panelling are 213 delicately framed blue gouache paintings. These are copies of originals by the French artists François Boucher and Jean Pillement
made by the children of the imperial couple Franz Stephan and Maria Theresa.
During the course of restoration work carried out in 2013, the surfaces of the wood panelling and the carved decorations were cleaned
in order to re-establish the porcelain-like impression of the room as a whole in its original quality.
For reasons of conservation the blue gouaches – hitherto erroneously referred to as ink drawings – will not be restored for the time being and instead will be
subject to longer-term monitoring. The objective is to develop a gentle method that can subsequently be used to treat the strong brown discoloration of the works.
