Fête des Lumières Lyon France

 
The Festival of Lights (French: Fête des lumières) in Lyon, France is a popular event, originally intended to express gratitude to Mary, the mother of Jesus, around December 8th each year. This unique Lyons tradition dictates that each house place candles along the outside of all
windows to create a spectacular streetscape. The festival includes other light-based activities and usually lasts for four days, peaking on the eighth. The two main focal points of activity are usually the Cathedral of Fourviere, which is lit up in different colors, as well as the Place de Trou, which hosts a different light show each year.
The origin of this festival dates back to 1643, when Lyon was attacked by the plague. On September 8, 1643, the municipal councilors (échevins) promised to pay homage to Mary if the city was saved. Since then, an official procession on December 8th (Feast of the Immaculate Conception) goes to Fourvere Church to light candles and give gifts in Mary's name. This event partly commemorates the day Lyon was consecrated to the Virgin Mary.
