Welcome to the Palais Garnier, an architectural marvel standing at the heart of the ninth arrondissement. As you stand here on the Rue Gluck, you are looking at what many call the most famous opera house in the world. This grand edifice is not just a theater; it is a monument to the secondary empire's luxury and the creative genius of Charles Garnier. Before you step inside, take a moment to admire the facade—a theatrical set in itself—adorned with seventeen different materials ranging from white marble to gilded bronze. This temple of music was born from tragedy: after a narrow escape from an assassination attempt at the old opera house in eighteen fifty-eight, Emperor Napoleon the Third ordered a brand-new, secure venue that would reflect the glory of Paris. Today, you are following in the footsteps of royalty and the social elite who once made this palace their second home.
