The National Museum in Warsaw (), popularly abbreviated as MNW, is a national museum in Warsaw, one of the largest museums in Poland and the largest in the capital. It comprises a rich collection of ancient art (Egyptian, Greek, Roman), counting about 11,000 pieces, an extensive gallery of Polish painting since the 16th century and a collection of foreign painting (Italian, French, Flemish, Dutch, German and Russian) including some paintings from Adolf Hitler's private collection, ceded to the museum by the American authorities in post-war Germany. The museum is also home to numismatic collections, a gallery of applied arts and a department of oriental art, with the largest collection of Chinese art in Poland, comprising some 5,000 objects. The museum boasts the Faras Gallery with Europe's largest collection of Nubian Christian art and the Gallery of Medieval Art with artefacts from all regions historically associated with Poland, supplemented by selected works created in other regions of Europe. History The National Museum in Warsaw was established on 20 May 1862, as the "Museum of Fine Arts, Warsaw", and in 1916 renamed "National Museum, Warsaw" (with the inclusion of collections from museums and cultural institutions such as the Society of Care for Relics of the Past, the Museum of Antiquity at Warsaw University, the Museum of the Society for Encouragement of the Fine Arts, and the Museum of Industry and Agriculture). The collection, on Jerusalem Avenue, is housed in a building designed by Tadeusz Tolwiński, developed between 1927 and 1938 (earlier the museum had been located at ulica Podwale 15). In 1932 an exhibition of decorative art opened in the two earlier erected wings of the building. The new building was inaugurated on 18 June 1938. The purpose-built modernistic edifice, was situated on the edge of Na Książęcem Park established between 1776–79 for Prince Kazimierz Poniatowski. From 1935 the museum director was Stanisław Lorentz, who directed an effort to save the most valuable works of art during World War II. During the invasion of Poland the building was damaged and after the Siege of Warsaw the collection was looted by the Gestapo led by Nazi historian Dagobert Frey, who had already prepared a meticulous list of the most valuable artwork on official visits from Germany in 1937. The Gestapo headquarters presented Rembrandt's portrait of Maerten Soolmans as a gift to Hans Frank in occupied Kraków and packed everything else to be shipped
