The Champ de Mars is now called the "Parc de la Marche" in Paris. This was probably to celebrate the 100th anniversary of the Eiffel Tower on March 31, 1989, and to commemorate the 100th anniversary of the Paris World Expo in 1889, as well as to meet the needs of the world's people in striving for world peace and fighting terrorism, and to meet the requirements of the surrounding environment. Near the Parc de la Marche are the UNESCO Building, the World Economic Cooperation and Development Organization; the French National Assembly Building, the Ministry of Foreign Affairs, the Ministry of Foreign Trade, the Ministry of Industry and other world organizations and state agencies. The Parc de la Marche makes people miss the history of the Eiffel Tower and the World Expo, which symbolize world peace.
