Saint-Fons is a French city next to Lyon. About 15.000 people live there. The name of the city does not come from a saint. It is because there are many fountains near the city. Originally the place name was Cent Fonts ( 100 sources), which was changed into the current city name. The city split from Vénissieux in the middle of the 19th century. The main reason for splitting was because of the chemical industry in the spot.
