Jaén is a city in south-central Spain, the capital of the province of Jaén in the autonomous community of Andalusia. It is the administrative and industrial centre for the province. Industrial establishments in the city include chemical works, tanneries, distilleries, cookies factories and textile factories. After the Moorish invasion of Spain during the 8th century, the city, then known as Jayyan, was developed as a trade centre. Remains of the Moorish fortifications and citadel still stand. Jaén is the seat of a Roman Catholic bishopric. Among the many points of interest is the Renaissance style cathedral, begun in 1532 and completed in the 18th century. Its population is 112,921 (2002), about 1/6 of the population of the province. Other important landmarks are the Castle, that can be seen from any point of the city, and the Arab Baths, the most significant remnants of the Moorish era of Andalusia. Jaén is also known as the World Capital of Olive oil, because it's the biggest producer of this liquid gold (as the locals refer to it). The football team of the city is Real Jaén and they play in the new Estadio de la Victoria.
