This is the former private room of Empress Maria Alexandrovna, wife of Emperor Alexander II. The room's sumptuous décor was designed in 1853 by the architect Harald Bosse, well-known for his skilful reinterpretations of Baroque interiors. The red brocatelle used for the curtains and on the walls and seats came from the Cartier Company in Paris. The ornatedraperies and upholsteries, the eleant patterns of ornaments and the soft gilt furniture create a luxurious and comfortable interior. The gilt bronze chandelier reflecting in the mirrors splendidly complements the overall decoration.
