The Champ de Mars is a large public greenspace in Paris, France, located in the seventh arrondissement, between the Eiffel Tower to the northwest and the École Militaire to the southeast. The park is named after the Campus Martius ("Mars Field") in Rome, which was dedicated to the god Mars. The name alludes to the fact that the lawns here were formerly used as drilling and marching grounds by the French military.
