 Prior to the Conquest, this site was reserved for the ritual known as "Dance of the Flyers" which is still practiced today in Papantla.Its ownership was in dispute during much of the colonial period, eventually becoming the site of a very large market known as El Volador.The interior of the building contains four panels painted in 1941 by José Clemente Orozco, two of which are named "The Social Labor Movement" and "National Wealth."
