Rosenborg Castle in Copenhagen is among the 10 best princely treasuries of Europe. It has been preserved in its original surroundings and about 95% of the more than 1000 objects have survived.
The first volume tells the history of the collection and ends with an art-historical summary of its contents. This account builds partly upon hitherto unknown evidence, for example travel diaries from foreign archives. The findings offer a new picture of royal political propaganda and of the making of Danish national identity.
The second and third volumes contain a catalogue raisonné. Each object is listed with an extract of the proper inventories, an illustrated description with reference to parallels abroad and a bibliography.
