Belvedere 21, formerly 21er Haus or Einundzwanziger Haus, 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". 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.

Museum of Military History
A huge museum featuring weapons and military maps from different periods. You can also see the open-top car in which Archduke Franz Ferdinand, the last Austrian prince, was shot in Sarajevo. His death triggered World War I and the eventual downfall of the Austro-Hungarian Empire. In the same room as this is the visibly blood-stained jacket he was wearing at the time of his assassination.
Austrian Gallery Belvedere
Contains recent Austrian and international art from the past two centuries. Viennese art from the early 20th century is well-represented in the permanent collection Vienna around 1900 and the Art of the Classical Modern, and includes masterpieces from Gustav Klimt, Oskar Kokoschka, and Egon Schiele, as well as earlier works by the Biedermeier painter Ferdinand Georg Waldmüller.
Botanic Gardens
Established in 1754 by Empress Maria Theresia as a garden for medicinal plants and granted to the University of Vienna, which has maintained it since. The gardens contain a number of rare plants, including alpine specimens.
Lower Belvedere / Orangery
The Lower Belvedere and Orangery house temporary exhibits. The Baroque state rooms including the Marble Gallery, Golden Room, and Grotesque Hall are open for normal visiting.
St. Marx Cemetery
This historic cemetery was in use from 1784 until 1874. Mozart was buried here in an unmarked pauper's grave in 1791; the tombstone dates from a later period, after his grave was tentatively identified. The Bezirksmuseum Landstraße offers regular guided tours of the cemetery (in German).
Soviet War Memorial
An imposing Soviet-style monument near Karlsplatz commemorates the Soviet victory in Vienna over the Nazi army.
