The "berlin modern" is currently being built at the Kulturforum in Berlin between the Neue Nationalgalerie and the Philharmonie. Among other things, the new museum will house the collections of the 20th century from the Neue Nationalgalerie. The Karlsruhe State Building Authority is managing the realisation of the new museum building for the client, the Prussian Cultural Heritage Foundation, based on a design by Swiss architects Herzog & de Meuron and Vogt Landscape Architects.
