Seville is the artistic, cultural, and financial capital of southern Spain. It is the capital of Andalusia and of the province of Seville. It is situated on the plain of the River Guadalquivir, with an average elevation of 7 metres (23 ft) above sea level. The inhabitants of the city are known as Sevillanos (feminine form: Sevillanas) or Hispalenses. The population of the city of Seville was 699,145 as of 2007 (INE estimate). The population of the metropolitan area (urban area plus satellite towns) was 1,450,214 as of 2007 (INE estimate), ranking as the fourth largest metropolitan area of Spain. The city's cathedral was built from 1401 - 1519 after the Reconquista on the former site of the city's mosque. It is amongst the largest of all medieval and Gothic cathedrals, in terms of both area and volume. The interior is the longest nave in Spain, and is lavishly decorated, with a large quantity of gold evident. The Cathedral reused some columns and elements from the mosque, and, most famously, the Giralda, originally a minaret, was converted into a bell tower. It is topped with a statue, known locally as El Giraldillo, representing Faith. The tower's interior was built with ramps rather than stairs, to allow the Muezzin and others to ride on horseback to the top.
