Lyon is the capital of the French administrative region of Auvergne-Rhône-Alpes. A city of half a million, Lyon alone is the country’s third-largest city, but its metropolitan area is only second in population to Paris. Lyon is mostly known as the gastronomic epicentre of France, with one of the highest concentrations of restaurants per capita in the country. Lyon was a Roman provincial capital and thus has extensive Roman ruins. Architecture in old Lyon ranges from 12th century.
