The Neue Nationalgalerie is a Berlin museum dedicated to 20th century art. It is located in the Kulturforum, the complex of cultural buildings in Berlin. Inaugurated in 1968, the museum is housed in a building designed by Mies van der Rohe, built entirely of steel (for the roof and the supports that support it) and glass (for the walls). The museum's collection derives from the Alte Nationalgalerie and includes works from the late nineteenth and first half of the twentieth century (while the more strictly contemporary art collection is located in the Hamburger Bahnhof) including works by artists such as Picasso, Klee, De Chirico , Dalì, Otto Dix and several others. The museum is surrounded by a large garden, which includes several abstract and figurative sculptures. The interior of the Neue Nationalgalerie covers an area of 5000 square meters, with 800 meters of walls, divided over two floors. The permanent collection is housed on the lower floor, while on the ground floor the numerous temporary exhibitions organized by the museum are held: here, on the ceiling, built like an enormous dark metal grid, LCD screens are installed that reproduce abstract subjects that scroll through the their entire length.
