The Palais Garnier, an architectural marvel in Paris, was inaugurated to much fanfare, establishing itself as one of the premier opera houses globally. The construction of the opera house began in 1861 under the orders of Emperor Napoleon III, part of his broader ambition to renovate Paris and enhance its cultural prestige. Designed by Charles Garnier, the building epitomizes the extravagance of the Second Empire style, showcasing a stunning façade adorned with a monumental grand staircase, gilded decorative elements, and a majestic chandelier that hangs gracefully in its grand foyer.

The opening performance featured Mozart's 'Don Juan,' which effectively celebrated the grand re-opening of the French opera scene, dominated previously by Italian influences. The opera house quickly became a preferred cultural hub, hosting numerous premieres and renowned performances that attracted patrons from high society and beyond. Its design also included cutting-edge technology for the time, such as an electric lighting system, enhancing the audience's experience.

The Palais Garnier was more than just a theater; it was a social hotspot where Parisian high society gathered, networks were formed, and artistic collaborations flourished. The venue allowed for varied performances, expanding beyond just opera to include ballet and concerts, significantly influencing the cultural landscape of the city. The inauguration not only marked a significant milestone in the arts but also represented Paris's ambitions to establish itself as a leading cultural capital in Europe during the late 19th century.
