View of Champ de Mars from the top of the Eiffel Tower

The Champ-de-Mars is a vast public area in Paris, France, located in the 7th arrondissement, between the Eiffel Tower to the northwest and the École Militaire to the southeast. Its name means "Field of Mars", from Mars the Roman god of war, because it was originally used for military training.

The Champ-de-Mars formed the setting of a massacre during the French Revolution on July 17, 1791. When a crowd collected to draft a petition seeking the removal of King Louis XVI, soldiers under the command of the Marquis de la Fayette opened fire, killing about 50 people.

The Champ de Mars is a public park in Montreal. Formerly a military parade ground, it is located in front of Montreal City Hall. It contains remnants of Montreal's fortifications.
