Guadalquivir Plain

The Guadalquivir Plain is a vast, flat alluvial lowland located in southwestern Spain. It is formed by the deposits of the Guadalquivir River, which flows from the Sierra de Cazorla mountains all the way to the Atlantic Ocean near Cádiz. The plain runs directly through the heart of the autonomous community of Andalusia.

Thanks to its flat landscape and rich soil deposits, the plain supports extensive and highly profitable farming operations. It is the primary region in Spain for cultivating olives, as well as sunflowers, wheat, and citrus fruits. The area also contains massive pig farming operations, particularly focused on raising the Iberian pigs used to make famous jamón ibérico.

Geologically, the plain is a large sedimentary basin that was originally a marine gulf before being filled in by river sediments over millions of years. The soil is largely composed of fertile alluvial loams and clays deposited by historical river flooding. The extreme flatness of the region is a direct result of this continuous alluvial deposition.

The Guadalquivir Plain runs right through the heart of Andalusia, containing several of the region's most historically significant cities. Major urban centers situated along the river and its plain include Seville (Sevilla) and Córdoba. These cities historically grew incredibly wealthy from the agricultural wealth generated by the surrounding plain.
