The Malachite Room (Alexander Briullov, 1839) served as the state drawing-room of Empress Alexandra Fiodorovna, the wife of Nicholas I. The unique malachite decoration of the room and many of its furnishings were made in the "Russian mosaic" technique. The large malachite vase and furniture produced to designs by Auguste Montferrand were among the furnishings of the Jasper Reception Room that perished in the 1837 fire. One wall of the room is embellished with an allegorical depiction of Night, Day and Poetry by Antonio Vighi. From June to October 1917 the Provisional Government met in this room. The display features 19th-century works of decorative and applied art.
