The Black Diamond (Danish: Den Sorte Diamant) is a modern waterfront extension to the Royal Danish Library's old building on Slotsholmen in central Copenhagen, Denmark. Its quasi-official nickname is a reference to its polished black granite cladding and irregular angles. Designed by Danish architects Schmidt Hammer Lassen, the Black Diamond was completed in 1999 as the first in a series of large-scale cultural buildings along Copenhagen's waterfront.
Apart from its function as a library, the building houses a number of other public facilities and activities, most of which are located around the central, toplit atrium which cuts into the building with a huge glazed front facing the harbour. The facilities include a 600-seat auditorium, the Queen's Hall, used for concerts—mainly chamber music and jazz—literary events, theatrical performances and conferences. There are also exhibition spaces, a bookshop, a restaurant, a café and a roof terrace. Two museums are based in the Black Diamond, the National Museum of Photography and a small museum dedicated to cartoon art.
In the early 1990s, the Danish Ministry of Cultural Affairs launched an international architecture competition for the design of an extension to the Royal Library on Slotsholmen. The competition attracted 178 Danish and international architectural firms and ultimately Schmidt Hammer Lassen was chosen as the winner in 1993.
Construction started in 1995. The cost of the building was DKK 465,000,000. The Ministry of Cultural Affairs was the builders and Moe and Brødsgaard A/S the consulting engineers.
The Black Diamond was inaugurated on 7 September 1999 and opened to the public on 15 September 1999. The Minister of Cultural Affairs at the time, Jytte Hilden, named it the Black Diamond.
The basic shape of the Black Diamond is a box which leans to the left as seen from the harbour as well as towards the water. At the same time it expands slightly from the bottom and up and from north to south, giving it a distorted, prismatic shape.
