Jaén is a city in south-central Spain, the name is probably derived from the Arabic word Jayyan, (crossroads of caravans). It is the capital of the province of Jaén. It is located in the autonomous community of Andalusia. The inhabitants of the city are known as Jiennenses. Its population is 117,540 (2006), about 1/6 of the population of the province. In the last years Jaén has had a great increase of cultural tourism. 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 urbanism of Jaén is determined by its adjustment to the hills of the Santa Catalina mountains, with steep, narrow streets, in the historical central city district. The city of Jaén is the administrative and industrial centre for the province. Industrial establishments in the city include chemical works, tanneries, distilleries, cookies factories and textile factories.
