The Neue Nationalgalerie, which was erected in 1965–68, is the only building by the architect Ludwig Mies van der Rohe in Germany from after the Second World War. With its steel roof over the glass-walled exhibition hall and its reduced design vocabulary, it is regarded as an icon of modernism and as the legacy of a visionary master builder. Following the restoration by the firm David Chipperfield Architects, the Neue Nationalgalerie is reopening with new glory in 2021. With numerous specialist texts and large-format photographs, the book focuses on the architecture of the museum in three thematic groups: the historical building, the fundamental restoration, and the renovated building. Detailed and large-format photographs heighten awareness of the unique architecture, which Mies van der Rohe designed down to the smallest detail.
