Gemäldegalerie, Berlin
Paintings and art were collected by the Prussian government, not through a royal dynasty. It's collection intended to give a European overview. The collection first opened in 1830 and expanded throughout the 19th century, adding over 1000 paintings and artworks. In 1904, the museum moved to Kaiser Friedrich Museum, today Bode Museum. Several art pieces that were not stored in shelters like larger altars were destroyed or looted during World War 2. The collection was separated into East and West Germany and reunited at the Kulturforum with the German reunification.
