Svetabel,
I'm amaze at the collection of items in this room! Pianos, stuffed bears, Chinese Porcellain, Stag horns and the amazing hanging boat! It must have been an amazing playroom for Alexander and Marie's children (and probably grandchildren).
Where all the pictures taken at the same time? It almost looks like some things were added (like display cases) when Gatchina was opened as a museum.
