Architect Josef Maria Olbrich built this Jugendstil (German-style Art Nouveau) building 1897-98 as a display space for artists working in the new Secession artistic movement. It is topped by a giant, frothy golden ball, lovingly called Krauthappel by the Viennese, but the building was definitely not loved when it first opened. Notice a reactionary Viennese pattern here? The opera building too was hated at first, but at least it was not called a "temple for bullfrogs" or "a bastard begot of temple and warehouse" as this building was. The entryway features the motto of the Secessionist movement: Der Zeit ihre Kunst, der Kunst ihre Freiheit (to the time, its art, to the art, its freedom). Olbrich's mentor Otto Wagner, and also Gustav Klimt, whose astounding Beethoven Frieze is partially preserved in the basement, inspired the building's design. The ceremonial front entrance is separate from the functional glass and steel exhibit hall in back.

The Vienna Secession (German: Wiener Secession; also known as the Union of Austrian Artists or Vereinigung Bildender Künstler Österreichs) is an art movement, closely related to Art Nouveau, that was formed in 1897 by a group of Austrian painters, graphic artists, sculptors and architects, including Josef Hoffman, Koloman Moser, Otto Wagner and Gustav Klimt.

They resigned from the Association of Austrian Artists (Vienna Künstlerhaus) in protest against its support for more traditional artistic styles. Their most influential architectural work was the Secession exhibitions hall designed by Joseph Maria Olbrich as a venue for expositions of the group. Their official magazine was called Ver Sacrum ('Sacred Spring'), which published highly stylised and influential works of graphic art. In 1905 the group itself split, when some of the most prominent members, including Klimt, Wagner, and Hoffmann, resigned in a dispute over priorities, but it continued to function, and still functions today, from its headquarters in the Secession Building. In its current form, the Secession exhibition gallery is independently led and managed by artists.
