A thoroughly modern library inside a grand, early 20th-century building where you can view important documents of Norway's cultural heritage, from 13th-century manuscripts to magazines, films and Norwegian musical scores. There are also temporary exhibitions highlighting often surprising aspects of the collection, covering such themes as the history of Norwegian black metal. Don't miss the Map Centre, a modern pod filled with maps charting how the Nordics have been represented in cartography over the centuries.
Second-floor Kafe Å is probably the calmest spot for coffee in Oslo.
