to Berlin. After the war the Polish Government, under the supervision of Professor Lorentz, retrieved many of the works seized by the Germans. More than 5,000 artifacts are still missing. Many works of art of, at that time unknown or of uncertain provenance (e.g. originating from Nazi German art repositories in Polish Recovered Territories in Kamenz, Karthaus, Liebenthal and Rohnstock among others) were nationalized by the communist authorities using subsequent decrees and acts from 1945, 1946 and 1958 and were included in the museum collection as so-called abandoned property. At present, the collection of the National Museum in Warsaw includes over 780,000 items displayed in many permanent galleries, including the Professor Kazimierz Michałowski Faras Gallery and galleries given over to ancient art, medieval art, painting, goldsmithing, decorative art and oriental art, as well as many temporary exhibitions. In 2008-2013 the "Polish Archaeological Mission "Tyritake" of National Museum in Warsaw" conducted works at Tyritake, Crimea. In 2016 the "Polish Archaeological Mission "Olbia" commenced works at Olbia (archaeological site), Ukraine. Both are headed by Alfred Twardecki curator of the Ancient Art Gallery. In 2010 the National Museum, as one of the first state institutions in the world, held an exhibition entirely dedicated to homoerotic art - Ars Homo Erotica. Since the 2011–12 renovation, the museum is also considered one of the most modern in Europe with a computer-led LED lighting allowing to enhance unique qualities of every painting and exhibit. In 1945 the National Museum took over the historic Nieborów Palace in the village of the same name and made them its subsidiaries. In the early perioid, the deputy curator there was the writer Mieczysław Smolarski. Permanent galleries In 2012 the permanent galleries underwent revolutionary changes. The curators of the museum re-arranged it and supplemented it with new works from the museum's warehouses. Paintings were not hung chronologically, but thematically: genre painting, still lifes, landscapes, cityscapes, biblical, mythological, nudes. Works by Italian, Flemish, Dutch, German and Polish artists were hung together, making it easy to observe and compare similarities and differences. The Gallery of Ancient Art, Faras Gallery, Gallery of Medieval Art, Gallery of Old Masters, Gallery of 19th-century Art and the Gallery of 20th and 21st-century, includes the works of Polish painters and sculptors and are displayed in the context of art in other countries and in different epochs. The galleries reflect the richness and diversity of traditions and historical experiences
