Seville is the capital of Andalucia and the cultural and financial centre of southern Spain. A city of just over 700,000 inhabitants (1.6 million in the metropolitan area, making it Spain’s 4th largest city), Seville is Andalucia’s top destination, with much to offer the traveler.

The city is situated on the banks of the smooth, slow Guadalquivir River, which divides the city into two halves: Sevilla and Triana. The Guadalquivir (known as Baetis by the Romans and as Betik Wahd-Al-Khabir by the Arabs) has had a major impact in the history of the city. The location of Seville is roughly coincident with the point where the Guadalquivir stops being useful for navigation. It is at this point that the cereal producing region of the Guadalquivir Valley starts, and Seville has acted as a sea-port for commerce of agricultural goods produced farther west. Intense trade existed in the area from Roman times, continued under Muslim rule, and exploded as Seville monopolized the new trade with the Americas. As the monopoly was broken and Cádiz largely took Seville’s place, the city entered a period of relative decline.
In the 19th century Seville gained a reputation for its architecture and culture and was a stop along the Romantic “Grand Tour” of Europe. Seville has built on its tourism industry since, playing host to the International Exposition in 1992, which spurred the construction of a new airport, a new train station, a bullet train link to Madrid, new bridges and improvements to the main boulevards. Tourist facilities are top-notch and the city is buzzing with festivals, color and a thriving nightlife scene. *
