« To every age its art, to art its freedom »— Joseph Maria Olbrich and the Secession movement, Inscription carved on the facade of the Secession Building, Vienna, 1897-1898
Your investigation begins at the Otto Wagner Pavilion, built in 1899 as the Karlsplatz subway station for the Vienna Stadtbahn. This Art Nouveau structure, with its gilded copper dome and marble facade, was restored between 1989-1991 and designated a UNESCO world architectural heritage site. Located in close proximity to the Karlskirche, it symbolizes the intersection of industrial modernity and Baroque heritage, a striking contrast characteristic of Vienna. It is here, beneath the gilded ornaments, that you receive your first directive, a cryptic message hidden by your contact before their disappearance.
The route then takes you to the Secession Building, an emblematic edifice constructed in 1897-1898 by architect Joseph Maria Olbrich. Its gilded laurel-shaped dome, 19 meters high, and the Art Nouveau inscription 'Der Zeit ihre Kunst, der Kunst ihre Freiheit' bear witness to the Secession movement, a creative hub for Gustav Klimt and Egon Schiele. In 2001, it was inscribed on the UNESCO World Heritage list. This building, restored in 1985-1986, served as a discreet meeting point for black market informants, as Viennese modernist artists often frequented the same circles as post-war smugglers.
You proceed towards Palais Schwarzenberg, a Baroque palace built between 1697 and 1723 by Lukas von Hildebrandt. With its 120-meter main facade and French gardens, this site served as the headquarters for the Allied Supreme Command from 1945-1955 during the four-power occupation of Austria. Secret agreements were negotiated within its walls, and spheres of influence were delineated, creating opportunities for the black market. Here, you search for documents left by a contact, hidden in the historical nooks of this monument, now a museum and cultural center.
Your quest leads you to the Kunsthistorisches Museum, a Renaissance edifice built between 1871 and 1891 by Gottfried Semper. Its facade, adorned with 16 statues of great masters, and its 40-meter dome house 270,000 works of art, including Jan van Eyck's 'Madonna of Chancellor Rolin'. Inscribed on the UNESCO World Heritage list in 2001, this museum is one of Europe's most significant. A contact was waiting for you here but left a clue leading to the Volksgarten. This public garden, created in 1823 after Napoleon's siege of 1809, features the Theseus Temple from 1820 and a Roses garden from 1895, symbolizing 19th-century liberal Vienna.
The itinerary concludes at the Schwedenbrücke, a steel bridge built in 1898 spanning the Blue Danube. Named in honor of Queen Christina of Sweden, this bridge was a strategic point during World War II and the Cold War, marking the separation of occupation zones. Restored in 1945, it bears commemorative plaques of the Austrian resistance. It is here, above the river, that the smuggling network carried out its most audacious exchanges. Your mission in Vienna culminates with the retrieval of incriminating evidence, a step closer to restoring order in this city marked by history and European architectural modernism.
