What is the champs de mars in France?
The Champ (singular) de Mars is the open space between the Eiffel Tower and the Ecole Militaire in Paris. It has been used for military parades, National festivals and World Fairs, including the one in 1889 to which the Tower was the gateway. At the time of the Revolution, the space was greater; a row of houses was built down each side at the end of the 19th Century.
