The Black Diamond is an extension of Royal Library's from 1999. The building is called The Black Diamond because its facade tilts out over the harbor, so when the sun is just right, it reflects off the water and onto the facade, making it look like it's shining, a bit like a diamond. 

Fun fact: The Royal library owns about 4,500 books printed before the year 1501.  

You can go to the library for a coffee break, study room or to just walk around.
