The National Library of Denmark was formed in 1648 by Frederick III while he was the king of Denmark and Norway. In 1482, the University of Copenhagen’s library was established. When these two institutions merged in 1989, their collection of materials exceeded 34 million, making it the biggest library in Scandinavia. This waterfront, modern glass building is the Royal Danish Library’s Black Diamond site. Den Sorte Diamant was built in 1999.
