This military institute of surgery and medicine was founded by Austrian ruler Joseph II and built in the late 18th century. He commissioned Tuscan craftsmen to create a collection of life-sized anatomical wax models as visual aids for future surgeons. Other items on display include antique medical instruments, documents, photographs, engravings, and a display case dedicated to Freud and other top Austrian psychoanalysts.

Vienna's Museum of Natural History is one of the world's largest natural history museums. It opened in the late 1800's and was designed to reflect the nature of the collections. The museum features a wide and varied collection of skeletons, fossils, precious stones, diamonds, meteorites, dinosaur casts and zoological exhibits. The most important pieces are a limestone fertility symbol, the "Venus of Willendorf," which is approximately 25,000 years old; and "Fanny of Galgenberg", which was found near Stratzing/Krems-Rehberg in 1988, and is one of the world's oldest sculptures, dating to approximately 32,000 BC.

Sigmund Freud lived and treated patients at this address from 1891 to 1938, when he left for London to flee from the Nazis. The museum occupies the apartment and includes many of the antiques the psychoanalyst collected during his lifetime, including all of the waiting room furniture. Glass cases contain letters, books, detailed notes and photographs, along with an audio-visual documentary about his family life narrated by his daughter, Anna, who was also a psychoanalyst.

The Austrian National Tobacco Company (Austria Tabak), founded in 1784 to preserve a state tobacco monopoly, administers this quaint museum.

One of the most recent timepieces is a 1992 computer clock.
