The Grand Staircase of the Palais Garnier, a 2,200-seat opera house in Paris, France. A grand landmark designed by Charles Garnier in the Neo-Baroque style, it is regarded as one of the architectural masterpieces of its time. The building was completed in 1874 as a replacement for the Théâtre de l'Académie Royale de Musique, which had been destroyed in a fire the year before.Photo credit: Benh Lieu Song
