Marble Palace one of the first Neoclassical palaces in Saint Petersburg, Russia. It is situated between the Field of Mars and Palace Quay,The palace was built by Count Grigory Orlov, the favorite of Empress Catherine the Great and the most powerful Russian nobleman of the 1760s. In 1785, Count Orlov fell out of favour with the Empress, who had the palace purchased for her own heirs. In 1797–1798 the structure was leased to Stanisław August Poniatowski, the last king of Poland. Thereafter the palace belonged to Grand Duke Constantine Pavlovich and his heirs from the Konstantinovichi branch of the Romanov family.During the Soviet era, the palace successively housed the Ministry of Labour (1917–19), the Academy of Material Culture (1919–36), and, most notably, the local head part of Moscow-based Central (=National) Lenin Museum (1937–91). Currently, the palace accommodates permanent exhibitions of the Russian State Museum, notably "Foreign Artists in Russia (18th and 19th centuries)" and the "Peter Ludwig Museum at the Russian Museum", featuring canvases by Andy Warhol and other Pop Art idols.
