Lyon (French pronunciation: [ljɔ̃] ( listen), locally: [lijɔ̃]; Occitan: Lion [liˈu]; Arpitan: Liyon [ʎjɔ̃]; English: /liːˈɒn/), traditionally spelt Lyons in English, is a city in east-central France in the Rhône-Alpes region, situated between Paris and Marseille. Etymologically it relates to the Celtic God Lugoves, Lugh as does Laon and Leiden. Lyon is located approximately 470 km (292 mi) from Paris, 320 km (199 mi) from Marseille, 420 km (261 mi) from Strasbourg, 160 km (99 mi) from Geneva, 280 km (174 mi) from Turin. The residents of the city are called Lyonnais.
The population of Lyon is 484,344 (2010). Together with its suburbs and satellite towns, Lyon forms the largest conurbation in France outside Paris, with a population estimated to be 1,422,331; its overall metropolitan area was estimated to have a population of 2,118,132. Its urban region represents half of the Rhône-Alpes region population with 2.9 million inhabitants. Lyon is the capital of this region, as well as the capital of the smaller Rhône département.
The Saône (French pronunciation: [soːn]; Arpitan Sona) is a river of eastern France. It is a right tributary of the River Rhône. Rising at Vioménil in the Vosges department, it joins the Rhône in Lyon.
The name "Saône" derives from that of the Gallic river goddess Souconna, which has also been connected with a local Celtic tribe, the Sequanes. Monastic copyists progressively transformed "Souconna" to "Saoconna", which ultimately gave rise to "Saône". The other recorded ancient names for the river were Brigoulus and Arar.
