The Palais Garnier can be compared to the Pantheon from Ancient Rome. Both works were symmetrical, which was an element of the Beaux-Arts style. The Palais Garnier has much more ornamentation, including festoons and cartouches, which the Pantheon lacks. The Palais Garnier also includes materials not accessible during Roman times like gold and metal. The metal was used for the large dome, which is another element of the Beaux-Arts style.
