« Vienna, the Red City »— Historic nickname linked to the red tiles of baroque rooftops
Michaelerplatz plunges you into the heart of Austrian imperial power, facing the main entrance to the Hofburg where Franz Joseph I had resided since 1848. This square, named after St. Michael's Church built between 1666 and 1672, was the silent theater of assassination preparations. Luigi Lucheni, Italian anarchist born in 1873, had studied the imperial court's comings and goings from this strategic position. The Neptune fountain, erected in 1737 by Giovanni Giuliani and standing 10 meters high, already dominated the scene when the assassin was scouting Empress Sisi's habits, married to Franz Joseph in 1854.
The Volksgarten reveals Vienna's other face: that of revolutionaries. This 19-hectare public garden, created in 1821 by order of Franz I as the first green space accessible to Viennese people, became a refuge for anarchists and 1848 agitators. Its Temple of Theseus, a 9-meter Ionic replica built in 1822, served as a rallying point for regime opponents. In these paths circulated the Italian revolutionary ideas that inspired Lucheni, nourished by anarchist writings distributed clandestinely from the immediate proximity of the imperial Hofburg.
Heldenplatz extends its 25,000 m² as a challenge to imperial authority. Opened in 1865 before the Hofburg, this monumental square welcomed after 1848 the echoes of European anarchist movements. The equestrian statue of Archduke Charles, 32 meters high with its pedestal and erected in 1860, contemplated the nationalist gatherings that agitated the Empire. At 300 meters from Michaelerplatz, Lucheni could observe the weaknesses of imperial security during public ceremonies, mentally preparing his fatal gesture of September 10, 1898.
The Austrian Parliament, built between 1874 and 1883 by Theophil Hansen in neoclassical style, embodies the political tensions of the late 19th century. Its 380-meter-long and 18-meter-high facade housed debates on anarchist questions that shook Europe. The Pallas Athena fountain, inaugurated in 1898 with its 8-meter sculptures by Arnold Irom, was completed the very year of Sisi's assassination. The political trials that followed the attack took place at the neighboring Justizpalast, a 50,000 m² neo-Renaissance palace of justice built between 1874 and 1881.
Your investigation in Vienna reveals how Italian anarchism penetrated the heart of the Austro-Hungarian Empire. From Rathauspark, theater of workers' meetings in the 1880s-1890s facing the 152-meter Gothic city hall completed in 1883, to the 2,600 rooms of the Hofburg where Sisi lived her final years, you have retraced the 240,000 m² of a declining empire. The empress's assassination on September 10, 1898 marked the end of an era: that of the Habsburgs who had reigned since 1279, swept away by the revolutionary winds of the dawning 20th century.
