It is an extensive parade ground, about 3,000 feet long and 1,500 feet wide, lying on the left bank of the Seine. There are four rows of trees on each side, and it is entered by five gates. It was finished in 1790, and in their eagerness to have it ready for the first great feast of the French Revolution, on July 14th, of that year, 60,000 volunteers, men and women, worked night and day for two weeks, and completed it in time. At this feast the king swore allegiance to the constitution. The Champs de Mars has been the scene of many great historic events. The World’s Fair of 1867 was held there.
