The Palais Garnier is a prominent Beaux-Arts style building that, like many Beaux-Arts buildings, is very reminiscent of Classical Antiquity. Particularly the Palais Garnier seems to draw inspiration from the Pantheon of Ancient Rome. The façade of the Palais Garnier is lined with pilasters, cartouches, and festoon-like appendages. This is reminiscent of a more ornamented version of the Pantheon façade. The pilasters act as the many pillars of the Pantheon and the cartouches, festoons, and other ornamentation acts like metopes and the triglyphs of the frieze. There is even a large triangular structure behind the dome that resembles the pediment of the Pantheon.
