The Hermitage Winter Palace served as the winter residence for every ruler of Russia since Peter III. Peter's mistress, the Countess Vorontsova, also had rooms in the grand Baroque palace. When his wife Catherine the Great seized the throne, she took possession of her husband's quarters and redecorated.
Nicholas I lived in a comparatively modest apartment in the Palace while his wife Alexandra did further decorating, commissioning the elaborate Malachite Room. Alexandra's exuberant room later became the meeting place for Kerensky's Provisional Government.
In July, 1917, the Provisional Government took up residence in the Hermitage Winter Palace, laying the foundation for the October Revolution. The Bolshevik government eventually transferred its capital to Moscow. Since that time, the Winter Palace has served as the renown Hermitage Museum.
