The Palais Garnier is a 1,979-seat opera house in Paris, France. The opera was constructed in what the architect Charles Garnier called the Napoleon III style; highly eclectic, and borrowing elements from the Baroque, the classicism of Palladio, and Renaissance architecture blended together. The facade and the interior followed the Napoleon III style principle of leaving no space without decoration. The building features a large ceremonial staircase of white marble with a balustrade of red and green marble, which divides into two divergent flights of stairs that lead to the Grand Foyer.
