The Ibero-American Exposition was held in Seville in 1929 to increase the ties between host Spain, Portugal and their former colonies. Each country built a pavilion and in contrary to most world expositions, the pavilions were built for the long term.
The centerpiece and administrative office of the world fair was the Plaza de Espana, designed by the Spanish architect Anibal González, who was also responsible for several other world fair pavilions. Today the structure is occupied by government offices and by the general office of the regional army.
