Bibliotheque Nationale by Labrouste falls under Beauxs Arts, which is characterized by its grand spaces, ornamentation, and symmetry. The ribbed vaults reappear here but this time they are decorated with cast iron finishing, and the walls and ceilings are made of reinforced plaster, which attributes its strength to the iron webbing inside. Other characteristics we recognize from the past include ionic capitals with volutes to symbolize wisdom.
