Lost in the colorful old streets of Lyon is France's second largest city, divided between the Old City and the New City. The Old City of Lyon is located at the foot of Mount Fuvier, on the west bank of the Thorne River, covering 24 hectares. It was a fishing village in ancient times, one of the world's largest silk production sites in the 15th century, and was the political, economic and cultural center of France in the 17th century. Today, the antique old town still presents Renaissance architecture, narrow streets, curved and undulating; Most of the houses are orange-red, red-tiled roofs and distinctive. As one of the largest Renaissance neighbourhoods in Europe, the entire Old City of Lyon was listed on the United Nations World Heritage List in 1998. After centuries of vicissitudes, the Old City of Lyon has become the city's most artistic neighborhood. Walking aimlessly along the inexpensive stone streets, through Renaissance-style buildings, as if in the middle ages, time seems to be here still, as if nothing has changed for centuries. The center of the old town is the 12th century St. Jean's Chief Cathedral, which runs from the church to St. Paul's Church on the north side, which is a recommended walking route.
