Context: The Champ de Mars ( French pronunciation :  (  d mas ) ; English : Field of 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 , a tribute to the Latin name of the Roman God of war . The name also alludes to the fact that the lawns here were formerly used as drilling and marching grounds by the French military . The nearest Métro stations are La Motte - Picquet -- Grenelle , École Militaire , and Champ de Mars - Tour Eiffel , an RER suburban - commuter - railway station . A disused station , Champ de Mars is also nearby . Originally , the Champ de Mars was part of a large flat open area called Grenelle , which was reserved for market gardening . Citizens would claim small plots and exploit them by growing fruits , vegetables , and flowers for the local market . However , the plain of Grenelle was not an especially fertile place for farming . The construction , in 1765 , of the École Militaire designed by Ange - Jacques Gabriel , was the first step toward the Champ de Mars in its present form . Grounds for military drills were originally planned for an area south of the school , the current location of the place de Fontenoy . The choice to build an esplanade to the north of the school led to the erection of the noble facade which today encloses the Champ de Mars . The planners leveled the ground , surrounded it with a large ditch and a long avenue of elms , and , as a final touch , the esplanade was enclosed by a fine grille - work fence . The Isle of Swans , formerly a riverine islet at the location of the northeastern foot of the Eiffel Tower , was , for the sake of symmetry and pleasing perspectives , attached to the shore . ( Note that the Isle of Swans discussed here should not be confused with the Isle of Swans that sits in the middle of the Seine downstream and around the next bend in the river , between the fifteenth and sixteenth arrondissements . ) Jacques Charles and the Robert brothers launched the world 's first hydrogen - filled balloon from the Champ - de - Mars on August 27 , 1783 . This place witnessed the spectacle and pageantry of some of the most well - remembered festivals of the French Revolution . On July 14 , 1790 , the first `` Federation Day '' celebration ( fête de la Fédération ) , now known as Bastille Day , was held on the Champ de Mars , exactly one year after the storming of the prison . The following year , on July 17 , 1791 , the massacre on the Champ de Mars took place . Jean Sylvain Bailly , the first mayor of Paris , became a victim of his own revolution and was guillotined there on 12 November 1793 . The Champ de Mars was also the site of the Festival of the Supreme Being on June 8 , 1794 . With a design by the painter Jacques - Louis David , a massive `` Altar of the Nation '' was built atop an artificial mountain and surmounted by a tree of liberty . The festival is regarded as the most successful of its type in the Revolution . The Champ de Mars was the site of Expositions Universelles in 1867 , 1878 , 1889 , 1900 , and 1937 ., The Atlantic Ocean is the second largest of the world's oceans with a total area of about .

The term itself is controversial and has divergent definitions in popular culture and in academia and has been an ongoing source of contention among scholars across several fields of study. In the sociological classifications of religious movements, a cult is a social group with socially deviant or novel beliefs and practices, although this is often unclear. Other researchers present a less-organized picture of cults on the basis that cults arise spontaneously around novel beliefs and practices. The word "cult" has always been controversial because it is (in a pejorative sense) considered a subjective term, used as an "ad hominem" attack against groups with differing doctrines or practices. Cults range in size from local groups with a few members to international organizations with millions., Alexandre Gustave Eiffel (born Bönickhausen ; 15 December 1832  27 December 1923) was a French civil engineer and architect. A graduate of École Centrale Paris, he made his name with various bridges for the French railway network, most famously the Garabit viaduct. He is best known for the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, and his contribution to building the Statue of Liberty in New York. After his retirement from engineering, Eiffel focused on research into meteorology and aerodynamics, and making significant contributions in both fields., Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight) which gives it a "grain" resembling wood, that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. A wrought product is one that has been mechnically worked by forging, extruding, rolling, hammering, etcetera, to change its form and properties. Wrought iron is a particular worked iron product that is seldom produced today as other cheaper, superior products have substituted., Bordeaux (Gascon Occitan: "") is a port city on the Garonne River in the Gironde department in southwestern France., The École Militaire ("Military School") is a vast complex of buildings housing various military training facilities located in the 7th arrondissement of Paris, France, southeast of the Champ de Mars., The Rhine (, , ) is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the
