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.
