The Royal Danish Museum merged with the University Library of Copenhagen in 1989 and was directly managed by the Danish Ministry of Culture, making it the "hardest library in the backstage" of Denmark. The Copenhagen Black Diamond is a very creative place named after the building itself’s smooth and bright black granite outer layer, which is as diamond-like when the canal’s light is reflected on the surface of the rock. The Black Diamond Library was built in 1999 as a extension of the Royal Library. Here you can see the manuscripts of the famous Danish master SrenKierkegaard, which are treasured in the Archives of the Royal Library SrenKierkegaard. Even the staff in the museum had only a small number of people who had access to the master's magnificent manuscript anthology, not to mention outside the museum. A large partition line divided the building into two parts, so that the atrium was filled with light. The atrium connects the city with the sea outside, and the old and new buildings of the library. The 1 metric ton/m iron frame beams lift up the glass walls. The 200 square meters of great paintings by famous painter PerKirkeby dot the ceiling of the Black Diamond Library. In addition to the usual main functions of the library, catering facilities are also provided, and a small bookstore is opened to serve readers and visitors who frequent the library. Here you can also find the National Photography Museum and a 600-seat Queen Music and Drama Hall. The hall offers views of the canal and boats and kayaks that travel between them. Opening hours: Monday to Saturday :08:00-19:00
