From Eiffel Tower to École Militaire, Champ de Mars is a magnificently designed urban green lung in Paris. As a central and large open space, Champ de Mars was chosen as the location for part of the French Revolution's celebrations and hosts the Expositions Universelles, Paris's famous World's Fairs. The place, which was open in 1780, is always bustling, full of Parisians and tourists who wish to enjoy the green lawns and superb view of the Eiffel Tower. It is an ideal place to absorb Paris's vibrant atmosphere, have a picnic, or just wander around in one of Paris's best areas.
