Seville, the capital of the region of Andalusia in Spain, has 11 districts, further divided into 108 neighbourhoods.
The Casco Antiguo (Spanish: Ancient Shell) is the old quarter of Seville, located in the centre of the city on the east bank of the Guadalquivir river. Principal tourist attractions are located here, such as the cathedral, the Alcázar, the Torre del Oro, the City Hall, the Palace of San Telmo, the Archivo General de Indias and the Metropol Parasol. Of its twelve neighbourhoods, El Arenal on the riverfront was the port of Seville until the Guadalquivir silted up in the 17th century, while the neighbouring Santa Cruz neighbourhood was a Jewish quarter until the Spanish Inquisition.
The University of Seville is mainly based in the former Royal Tobacco Factory in the south of the Casco Antiguo, the setting to the story and opera Carmen. The city's bullring is in El Arenal.
