The story that haunts this land
Your investigation begins at the Michaelertor, baroque portal completed in 1881 by Ferdinand Stadl, guarding the main entrance to the Hofburg since Charles VI's reconstruction in 1723-1735. This main Habsburg residence from 1279 to 1918 spans 18 wings and 2,600 rooms, theater of Franz Joseph I's final days. You cross this threshold where imperial funeral processions passed, carrying remains to their final rest in the Kaisergruft.
At Michaelerplatz, square formed in 1889 during the demolition of medieval ramparts, you discover the nerve center of Habsburg ceremonies until 1918. Saint Michael's Church, built from 1665 to 1724, gave its name to this esplanade where Maria Theresa was crowned empress in 1740. The cobblestones preserve the imprint of imperial carriages that led sovereigns from the Hofburg to their eternal sepulcher.
The Augustinerkirche, Gothic church founded in 1327 by Frederick II the Fair of Habsburg, houses the tomb of Maria Theresa and Francis I, sculpted in 1765 by Balthasar Ferdinand Moll. In this single nave 28 meters high, Habsburg funeral ceremonies preceded their transfer to the Kapuzinergruft. You walk on flagstones where the dynasty's final requiems resonated, before processions crossed Vienna toward the Capuchin crypt.
Josefsplatz, completed in 1754 and named after Joseph II in 1780, reveals the equestrian statue of the reformer emperor, 5.5 meters high and sculpted in 1806 by Franz Anton von Zauner. This square was formerly a public execution site until the 18th century, before becoming the heart of the Habsburg winter palace. The adjacent National Library, built from 1723 to 1730, preserves the dynasty's secret archives that you consult in your mission.
Your journey ends at the Kapuzinerkirche, built from 1614 to 1617 by order of Matthias, guarding access to the Kaisergruft. This 1,700 m² imperial crypt maintained at 12°C houses 52 Habsburg sovereign sarcophagi since 1633, including Franz Joseph's in 1916. You carry away the secrets of six centuries of imperial power, engraved in Vienna's stone and whispered by the ghosts of Europe's longest dynasty.
