The city of Lyon is situated in east-central France in the
Rhône-Alpes region, at a distance of about 470 km from Paris. Two rivers, the Rhône and the Saône, flow through the city and merge south of the historic city center, which derives its nickname, the peninsula (
Presqu'île), from this fact. Two large hills dominate the topography of the city, one west of the center on the other side of the Saône (
Fourvière) and the other one (
Croix-Rousse) in the north. A large plain, which is the location of the modern part of Lyon including its urban center with the Part-Dieu railway station, lies across the Rhône in the east and is home to most of the city's population. Lyon itself has about half a million inhabitants; the greater Lyon area, which includes Villeurbanne with the UCBL campus and Ecully with the École Centrale, has a total population of around 1.5 million.
Lyon was founded as a Roman colony on the Fourvière hill in 43 BC, with its original name
Lugdunum being derived from a Gaulish settlement in the same area. The village quickly gained importance due its trade-friendly location on two navigable rivers and the main land route from south-eastern to northern France. Lyon became a major economic center in the late middle ages and started to develop the silk trade during the renaissance, which continued to be a major industrial factor well into the nineteenth century. Today Lyon is the second-largest economic center in France (chemical and biotechnological industry, banking) and an
innovation city, but it has also preserved its historical charm and architectural landmarks; its districts Fourvière, Vieux-Lyon (the renaissance quarter), Croix-Rousse, and the Presqu'île together form a UNESCO World Heritage Site.
Lyon is located in a transition zone between oceanic and humid subtropic climate; the average high/low temperatures are 6.2°C/0.2°C in January, the coldest month, and 27.0°C/15.6°C in July, the hottest month. The average precipitation per month varies between 50 mm in wintertime, 60-80 mm during summer, and 70-95 mm in spring and autumn.
