The Art Nouveau pavilion was erected in 1898 in the course of Stadtbahn construction. Otto Wagner planned two portal buildings of identical design. Today, the Wien Museum uses the west pavilion, where the trains once left for Hutteldorf.
Wagner's design was revolutionary. The many decorative details make the station into a prime example of Viennese art nouveau. Metal and wood were painted apple-green, the signal colour of the Stadtbahn. Gold, and finest white marble were added on the exterior.
The planning for the underground rail junction of Karlsplatz in the late sixties threatened the pavilion with demolition. Protests followed; the station building was dismantled and re-erected in 1977, but elevated 1.5 m above its old level on the square. Now at last the west pavilion is paying Otto Wagner the homage due to him - with the new Otto Wagner Documentation exhibition.
