Mozart's Final Secret — Decode the Requiem

Your investigation begins on Michaelerplatz, a historic 17th-century square in front of the Hofburg's main entrance. In the center, the equestrian statue of Emperor Charles VI, erected in 1723 by Jean-Étienne Liotard, observes you. Flanked by the Neptunbrunnen and Providentiabrunnen fountains, sculpted by Dominik Hildebrandt in 1737, this square was the scene of imperial Habsburg ceremonies. The Michaelerkirche, a Gothic church built between 1358 and 1394, dedicated to Archangel Michael, houses the empty tomb of Emperor Frederick III since 1463, a key Austrian historical monument. It is here, in the shadow of the baroque facade added in 1724-1730 by Jean-Nicolas Jadot, that the first clues about Mozart's secret life are revealed.

As you head towards Josefsplatz, an 18,000 m² square courtyard of the Hofburg, named after Emperor Joseph II, you discover a new facet of Vienna's history. In the center, the equestrian statue of Joseph II, cast in 1807 by Franz Anton von Zauner, dominates the space. The adjacent Austrian National Library was founded in 1726 by Charles VI, a place of knowledge where Mozart might have sought answers. This square, once the Habsburg winter palace since 1665, witnessed court intrigues that may have influenced the Requiem's mysterious commissioner. Your path then leads to Mozarthaus Vienna, where the composer lived, a key site for understanding his musical genius.

The itinerary then takes you to Stephansdom, Vienna's main Gothic cathedral, whose construction began in 1137 and the nave was completed around 1430. Its 111 m long tiled roof, depicting the Austrian coat of arms since 1952, holds secrets. The south tower (Steffl), 136.4 m high and ascended by 343 steps since 1433, offers a view over the city of Vienna. Here lies the mausoleum of Frederick III, sculpted by Niclas Gerhaert de Leyde between 1466 and 1513. This major monument of Vienna's heritage, a prominent Gothic cathedral, is a convergence point for the clues you are following, revealing unexpected links between the composer and the ancient imperial dynasty.

Your journey leads you to the Pestsäule, the Baroque Holy Trinity Column erected in 1694 by Leopold I to give thanks for the end of the 1679 plague. Standing 21.1 m high, sculpted by Paul Strudel and his workshop, it is located on Graben, a pedestrian shopping street since 1973. This major work of Austrian Baroque, restored in 2006, symbolizes the faith and resilience of the city of Vienna. While the column is not directly linked to Mozart, it represents a testament to the life and beliefs of the era, an essential context for understanding the composer's anxieties and inspirations. It prepares you for the solemnity of the Augustinerkirche.

The Augustinerkirche, a Gothic church of the Augustinians built from 1320 to 1350, is your next stop. It houses the tombs of empresses, including Maria Theresa (1717-1780) and Elisabeth (1837-1898), and its 40 m long choir is among the largest in Austria. A site of imperial weddings, including that of Franz Joseph in 1854, the Augustinerkirche is an essential Austrian historical site.
