The New Burg has an archive and three collections of the Museum of the History of Art: the Armory Collection (Hofjagd- und Rüstkammer), the Collection of Old Musical Instruments (Musikinstrume ntensammlung) and the Ephesus Museum (Ephesos Museum).
The Vienna Arms Collection contains one of the best collections of weapons and armor in the world. In addition, it is the best documented collection in the Western world, since the exhibits were usually created or acquired in connection with important political events: on the occasion of military campaigns, coronations, engagements, weddings, etc. The Habsburgs were bound by marriage with the rulers of many European countries, therefore, the collection contains armor and decorative weapons of almost all Western European rulers of the 15-20 centuries. The collection was started back in the 16th century by a passionate collector of Archduke Ferdinand of Tyrol. The most valuable exhibits are the armor of Frederick the Victorious (1450 g, gunsmith Tomaso Misalya), military equipment of Maximilian I (1495 g, gunsmith Lorenz Helmschmid), the work of the famous gunsmiths Konrad Zeusenhofer and Filippo Negloli.
The Vienna Renaissance musical instrument collection is the largest in the world. In addition, the museum presents numerous instruments played by famous musicians and composers, as well as works by famous masters. The collection includes unique instruments, as well as a full range of clavichords and pianos. A feature of the museum is that the sound of instruments can be listened to in the recording. The most valuable exhibits are Rebeccino in the form of the goddess Venus of the 15th century, Viol d'amur of the 18th century, a lyre-sistre (a theorba with the characteristics of a cifara, made in the form of an antique lyre) 16th, a double guitar by Alexander Woboam 17th, the counter-guitar by Johann Anton Staufer 19 c, rare keyboards and wind instruments, a miniature organ fletenwerk.
The Ephesus Museum stores artifacts discovered by Austrian archaeologists during excavations of the ruins of Ephesus and exported from the territory of modern Turkey in 1895-1806. The museum contains an extensive collection of Greek and Roman antiquities. Among them are the 40-meter Roman Parthian frieze (161-165), part of the altar from the temple of Artemis (4th century BC), a bronze statue of an athlete and a child with a goose (4th century BC), etc. Along with with ephesian artifacts, the museum also houses architectural monuments and sculptures from the sanctuary of the Greek island of Samothrace, which was studied by Austrian archaeologists in 1873 and 1875.
