Museum of Military History, Vienna

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

The Österreichische Galerie Belvedere is a museum housed in the Belvedere palace, in Vienna, Austria. The Belvedere palaces were the summer residence of Prince Eugene of Savoy (1663–1736). The ensemble was built in the early eighteenth century by the famous Baroque architect, Johann Lucas von Hildebrandt, and comprises the Upper and Lower Belvedere, with the Orangery and Palace Stables, as well as extensive gardens. Today, the Belvedere houses the greatest collection of Austrian art dating from the Middle Ages to the present day, complemented by the works of international artists. At the Upper Belvedere, visitors not only encounter artworks drawn from over five hundred years of art history but can also experience the magnificent staterooms. In addition to the Lower and Upper Belvedere, the museum has further sites at Prince Eugene's town palace and the 21er Haus as well as the Gustinus Ambrosi Museum. The Belvedere's art collection presents an almost complete overview of the development of art in Austria and, thus, an insight into the country's history. The world's largest collection of Gustav Klimt's paintings lies at the heart of the presentation of Art around 1900, on show at the Upper Belvedere. Its highlights are Klimt's paintings, The Kiss (1908) and Judith and the Head of Holofernes (1901), and masterpieces by Egon Schiele and Oskar Kokoschka. Key works of French Impressionism and the greatest collection of Viennese Biedermeier art are further attractions at the museum.

The grounds are set on a gentle gradient and include decorative tiered fountains and cascades, Baroque sculptures, and majestic wrought iron gates. The Baroque palace complex was built as a summer residence for Prince Eugene of Savoy. The Belvedere was built during a period of extensive construction in Vienna, which at the time was both the imperial capital and home to the ruling Habsburg dynasty. This period of prosperity followed on from the commander-in-chief Prince Eugene of Savoy's successful conclusion of a series of wars against the Ottoman Empire.
