Known as the greatest house of culture in Mexico, the Palacio de Bellas Artes was built upon the site of the first National Theatre, in anticipation of the 100th anniversary of Mexico's independence from Spain. Issues related to the soft subsoil as well as political unrest during the Mexican Revolution necessitated several delays and construction was not completed until 1934. The exterior of the building is done primarily in the Neoclassical and Art Nouveau styles while the interior is predominantly Art Deco.

One of the most iconic monuments in Mexico City, he building has and continues to host some of the most noteworthy performances and exhibitions.
