Seville (Spanish: Sevilla) is a Spanish city, the capital of the autonomous community of Andalusia and the province of Seville and the third-largest city in Spain. It is situated on the lower reaches of the Guadalquivir River, in the southwest of the Iberian Peninsula. Seville has a municipal population of about 700,000, and a metropolitan population of about 1.5 million, making it the largest city in Andalusia, the fourth-largest city in Spain and the 30th most populous municipality in the European Union. Its Old Town, with an area of 4 square kilometres (2 sq mi), contains three UNESCO World Heritage Sites: the Alcázar palace complex, the Cathedral and the General Archive of the Indies. The Seville harbour, located about 80 kilometres (50 miles) from the Atlantic Ocean, is the only river port in Spain.
Seville is the most populated city in southern Spain, and has the largest GDP (gross domestic product) of any in Andalusia, accounting for one quarter of its total GDP. All municipalities in the metropolitan area depend directly or indirectly on Seville's economy, while agriculture dominates the economy of the smaller villages, with some industrial activity localised in industrial parks. The Diputacion de Sevilla (Deputation of Seville), with provincial headquarters in the Antiguo Cuartel de Caballería (Old Cavalry Barracks) on Avenida Menendez Pelayo, provides public services to distant villages that they can not provide themselves. The University of Seville and the University Pablo de Olavide are important centres of learning in western Andalusia as they offer a wide range of academic courses; consequently the city has a large number of students from Huelva and Cádiz.
The economic activity of Seville cannot be detached from the geographical and urban context of the city; the capital of Andalusia is the centre of a growing metropolitan area. Aside from traditional neighbourhoods such as Santa Cruz, Triana and others, those further away from the centre, such as Nervión, Sevilla Este, and El Porvenir have seen recent economic growth. Until the economic crisis of 2007, this urban area saw significant population growth and the development of new industrial and commercial parks.
