Champ de Mars (Paris, France), as seen from the observation deck of the Eiffel Tower. In the distance is Tour Montparnasse and the dome on the left is Les Invalides. The École Militaire is at the end of the Champ de Mars. In English the name means "Field of Mars", from Mars the Roman god of war, from its original use for military training. During the French Revolution, the Champ de Mars was the setting of the Fête de la Fédération, on 14 July 1790.Photo credit: David Iliff
