In such a depressed state, he threw himself into composing. Two of his best-known operas were written at the time: "The Marriage of Figaro" and "Don Giovanni." Kammermusikus' place at the imperial court also became vacant, Christoph Willibald Gluck died, and Mozart was hired in his place. Until the end of his days, Mozart lived in Vienna. To this day, you can still see one of his apartments at Domgasse 5 near St. Stephen's Cathedral, where Amadeus composed "The Marriage of Figaro."
