The Arsenal is a former military complex of buildings in the south-east of Vienna in the third district. Several brick buildings in a rectangle layout make up the complex which is located on a bank south of the Landstraßer Gürtel. It is the most distinguished building group of Romantic historicism in Vienna and has been constructed in Italian-medieval and Byzantine-Islamic style. Essentially the complex is still preserved in its original form, merely a few workshop buildings within the courtyard were replaced.

The Museum of Military History – Military History Institute (German: Heeresgeschichtliches Museum – Militärhistorisches Institut) in Vienna is the leading museum of the Austrian Armed Forces. It documents the history of Austrian military affairs through a wide range of exhibits comprising, above all, weapons, armours, tanks, aeroplanes, uniforms, flags, paintings, medals and badges of honour, photographs, battleship models, and documents. Although the museum is owned by the Federal Government, it is not affiliated to the Federal museums but is organised as a subordinate agency reporting directly to the Ministry of Defence and Sports.

Central European University (CEU; German: Zentraleuropäische Universität, Hungarian: Közép-európai Egyetem) is a private research university with campuses in Vienna, Budapest, and New York. The university offers intensive graduate and undergraduate programs in the social sciences and humanities, and is known for its low student-faculty ratio, and a highly diverse international student body. Admissions are classified as highly selective with an acceptance rate of 13%. All CEU programs and courses are accredited in Austria, Hungary and the United States. CEU was founded in 1991 by hedge fund manager, political activist, and billionaire philanthropist George Soros, who provided it with an $250 million endowment in 2001, making the university one of the wealthiest in Europe, especially on a per-student basis. The university was founded in Central Europe because of a perceived need for an independent and international university for the region, in light of the fall of the Socialist Bloc and concomitant democratisation. A central tenet of the university's mission is the promotion of open societies, a result of its close association with the Open Society Foundations. CEU is a part of The European University of Social Sciences (CIVICA). The CIVICA Alliance is a group of 10 prestigious European higher education institutions in the social sciences, humanities, business management and public policy, such as Sciences Po, The London School of Economics and Political Science, Bocconi University and the Stockholm School of Economics.

Belvedere 21, formerly 21er Haus or Einundzwanziger Haus (English: House 21), is a modernist style steel and glass building designed by Austrian architect Karl Schwanzer (1918–1975). Originally constructed as the Austrian pavilion or temporary showroom for the Expo 58 in Brussels, it was later transferred to Vienna to house the Museum of the 20th Century, which explains why it was first nicknamed "20er Haus" (House 20). Between 1979 and 2001, the building also acted as a depository for contemporary art works. From 2009 to 2011, it was remodeled by the architect Adolf Krischanitz and consequently renamed 21er Haus to reflect the 21st century. It was renamed Belvedere 21 in 2018.

The Palais Lanckoroński was a palace in Vienna, Austria, located at Jacquingasse 16-18, in the Landstraße District. It was constructed in 1894-95 for Count Karol Lanckoroński and his family as a personal residence, and it housed the count's enormous art collection. The palace was built in a neo-baroque style by the theatre architects Ferdinand Fellner and Hermann Helmer. The building was three stories high, set back from the street, and protected by a wall with double gates. The entrance hall was wood panelled, two stories high, and decorated with portraits of the family. Other festive halls were decorated with frescoes and luxurious gobelin tapestries from the 17th century. Precious paintings, furniture and sculpture from different eras were arranged to form themed ensembles in the various rooms, with the rooms named to reflect the collection housed within. The palace was severely damaged in World War II, and was torn down in the 1960s.

The Botanical Garden of the University of Vienna is a botanical garden in Vienna, Austria. It covers 8 hectares and is immediately adjacent to the Belvedere gardens. It is a part of the University of Vienna. The gardens date back to 1754 when Empress Maria Theresa founded the Hortus Botanicus Vindobonensis with renowned botanist Nikolaus von Jacquin as one of its first directors. His son, Joseph von Jacquin, succeeded him as director, as did a number of other leading botanists in turn, including Stefan Endlicher, Eduard Fenzl, Anton Kerner von Marilaun, Richard von Wettstein, Fritz Knoll, Karl von Frisch, and Lothar Geitler. The Institute of Botany building was opened in 1905. However, at the end of the Second World War, the institute, all the greenhouses, and the entire garden area were bombed and severely damaged, and thus required major repair work. The gardens currently contain more than 11,500 species of plants, including well-documented tropical plants, particularly of such families as Annonaceae, Rubiaceae, Gesneriaceae, Bromeliaceae or Orchidaceae. Its greenhouses (ca. 1,500m²) were originally built between 1890 and 1893, but were damaged during the Second World War; they were renovated or rebuilt between 1970 and 1995. Only the tropical greenhouse in the centre of the complex is open for the public. The garden collections include: Abies pinsapo Aesculus pavia Asimina triloba Cephalotaxus harringtonia Diospyros lotus Elaeagnus angustifolia Ephedra Ficus carica Ginkgo biloba Gunnera chilensis +Laburnocytisus adamii Liriodendron tulipifera Magnolia Metasequoia glyptostroboides Nothofagus antarctica Ostrya carpinifolia Paeonia Parrotia persica Paulownia tomentosa Phyllostachys viridiglaucescens Pinus aristata Platanus orientalis Poncirus trifoliata Prunus tenella Rhododendron Salvia Sequoiadendron giganteum Syringa Viburnum Vitis riparia
