France's second largest city, with a long history and glorious tradition, is well known for its Marseilles. The old port of Marseilles is the essence of Marseilles. The Castle of St. John and the Castle of St. Nicholas on both sides of the port are representative buildings of the Louis XIV period, with extraordinary momentum, guarding the main entrances and exits of the port. The harbor is quiet, the streets are open, and there are many shops in the fish market, which is a secular and prosperous scene. There are castles, museums, churches and many other cultural relics around the port, which deserve to be carefully visited!
