The Neue Nationalgalerie (New National Gallery) is a museum for modern art in Berlin, with its main focus on the early 20th century. The building and its sculpture gardens were designed by Ludwig Mies van der Rohe and opened in 1968.
Its structure consists of a large steel “waffle” roof deck supported by eight exterior columns, creating an effect of a shelter with a single floating plane. Large glass sheets that define the interior space are set far back from the roof edges, framed by delicate steel mullions. The glass walls and the elimination of all interior columns emphasizes the idea of free space as a place for artists to present their work, unencumbered by the necessity of a shelter to protect visitors and contents from the elements, a symbolic removal of solid walls as barriers.
