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.Two tall towers at each end are connected to a central structure by a long colonnaded gallery. Its curved facade follows the contours of a semicircular plaza with a large central fountain. The plaza is surrounded by a canal, and beautiful bridges decorated with ceramic tiles connect the plaza with the wide promenade that runs along the front of the building.
