The most worthwhile visit to Marseille is the Cathedral of the Virgin of the Virgin, on the high ground of the city, and the fortress of St. John, which was built during the Louis XIV period and is held close to the throat of Marseille's old port to the Mediterranean. The castle is a beautiful view of the blue sky and blue sea of the Mediterranean Sea and the charming harbor of Marseille. The castle is connected by an aerial iron bridge to the Mediterranean Civilization Museum, which combines classical and modern organically and has a good visual experience. The castle is free to visit, but museum visits are charged.
