The city is known for its historical and architectural landmarks and is a UNESCO World Heritage Site. Lyon was historically known as an important area for the production and weaving of silk and in modern times has developed a reputation as the capital of gastronomy in France. It has a significant role in the history of cinema due to Auguste and Louis Lumière who invented the cinematographe in Lyon. The city is also known for its famous light festival 'Fete des Lumieres' which occurs every 8 December and lasts for four days, that earned Lyon the title of Capital of Lights (not to be mixed up with Paris the city of light). The legend says that the Virgin Mary saved the city from the plague, and to thank her a statue was built and on the day it was erected the whole city was lit by candles that its citizens put at their windows.
