The Palais Garnier owes its existence partly to a bomb — an 1858 attempt on Napoleon III's life convinced the emperor he needed a grander, safer opera house. A little-known architect, Charles Garnier, beat 170 rivals to the commission and spent fourteen years wrapping the building in coloured marble, gilt bronze, and a facade crowded with muses and gold-winged figures. Asked what style it was, Garnier reportedly answered simply: Napoleon III — his own. It opened in 1875, and its lavish Second Empire manner was copied by opera houses from Warsaw to Manaus for decades afterwards.
Inside, the Grand Staircase is the main event, a double sweep of white and green marble built so that the audience could watch itself arrive. A seven-tonne chandelier hangs over a red-and-gold horseshoe auditorium, crowned since 1964 by a Chagall ceiling of floating lovers and composers. Below the stage sits the water tank that fed the Phantom legend. Today the ballet mostly performs here while opera moved to the Bastille, and between shows you can wander the mirrored, chandelier-lit foyers that were built to rival Versailles.
