National Museum, Wrocław
The National Museum in Wrocław (), established 28 March 1947 and officially inaugurated on 11 July 1948, is one of Poland's main branches of the National Museum system. It holds one of the largest collections of contemporary art in the country. The holdings of Wrocław Museum are closely connected with the history of border shifts in Central Europe following World War II. After the annexation of Eastern half of the Second Polish Republic by the Soviet Union, main parts of Poland's art collections were transferred from the cities incorporated into the USSR like Lviv. Collections not  returned included the Ossolineum holdings which became part of the Lviv National Museum. The cultural heritage shipped in 1946 included Polish and European paintings from 17th to 19th centuries. Conclusion of World War II. Most historic buildings in Wrocław were destroyed or heavily damaged in World War II (see: the Siege of Breslau). The new Polish Department of Museums and Heritage Protection ("Referat Muzeów i Ochrony Zabytków", RMOZ) was entrusted with the task of selecting a suitable placement for the newly arriving cultural artifacts. The relatively undamaged location was chosen on among the ruins of the old city center, at  the former Silesian regency office built in 1883–1886. Although the location of the National Museum and its collections were new in Wrocław, the actual tradition of art museums in the city was centuries old. Its predecessors included the Royal Museum of Art and Antiquity formed in 1815 () and the Silesian Museum of Fine Arts created in 1880, as well as the Silesian Museum of Applied Arts formed in 1899. When Poland disappeared from the map of Europe at the end of the 18th century many artifacts produced by Polish artists and artisans were also displayed there. Permanent exhibits. Admission to  the gallery is free on Saturdays. Among the permanent exhibitions set up on different floors of the Museum are four distinct departments divided by art-periods and historical epochs.
