La biblioteca Reale "Diamante Nero" a Copenhagen, Danimarca. Deve il suo nome per il granito nero dello Zimbabwe che caratterizza la facciata.

The Royal library Black Diamond at the waterfront of Copenhagen owes its name to the black granite from Zimbabwe used for the facade of the building. The name
was used by the public first and has been adapted officially later. Design by the Danish architects Schmidt, Hammer & Lassen.
