Garnier's works represent a Neo-Baroque-inspired style, popular during the Beaux-Arts period in France. He was influenced by the Italianate styles of Renaissance artisans such as Palladio, Sansovino, and Michelangelo, perhaps the result of his many visits to Greece and Rome during his lifetime. He was also a pioneer of architectural beauty as well as function; his opera was built on a framework of metal girders, unprecedented at the time. Aside from being fireproof, steel and iron was much stronger than wood, allowing it to successfully withstand the countless heavy tons of marble and other materials heaped upon it without breaking.
