It was originally established as a national museum in 1926 and later on as the State Museum of Montenegro. Today, it is predominantly of a memorial character, with the emphasis on the royal court as a political institution, created particularly at the level of state development, and its role in the foreign relations of the country. The museum has tens of thousands of exhibits distributed in archaeological, ethnographic and art collections as well as collections of medals, weaponry, plaquettes, seals, emblems, flags and photographs. The museum also has a court library with 10,000 rare books, among which are two Books of Psalms - "First-voice" and "Fifth-voice Octoechoes"
