The Black Diamond is the name given to the modern wing of the Royal Library, inaugurated by Queen Margrethe in 1999. The nickname originates from the building’s façade, crafted from polished black granite from Zimbabwe. Contrasting with the historic main wing of the library, which houses documents and books dating back to the 17th century, the Black Diamond is a decidedly modern venture. It houses a concert hall, as well as the National Museum of Photography and the International Authors’ Stage, which hosts such renowned writers as Salman Rushdie and Philip Pullman. Dining is available at Søren K on the ground floor.
