The Black Diamond

Designed by Danish architects Schmidt Hammer Lassen and opened in 1999, the Black Diamond is an extension to the Royal Library in Copenhagen that doubles its size. Its exterior of two glossy black cubes slightly tilted over its harbour-front walkway, reflect the sky above and the sea before it.

This glass-and-black-marble structure, which changed the face of the city’s harbour, features a stunning eight-story atrium, whose undulating walls and balconies echo the ebb and flow of the harbour’s waterway.
