The most emblematic building of the Iberoamerican Exposition held in Seville in 1929 is also the most representative structure built in the Spanish regionalist style. The main structure is a semi-circular square measuring 200-metres in diameter symbolizing the embrace of Spain to its former American colonies, topped with two towers of 74 meters, a central fountain, four bridges representing the four kingdoms of Spain and a collection of cloths tiles on the Spanish provinces.
