The Champ de Mars and the Trocadéro in Paris

Located in Paris's 7th arrondissement, the Champ de Mars is a vast public park stretching 780 meters (2,559 ft) between the Eiffel Tower and the École Militaire. Its address is 2 Allée Adrienne Lecouvreur, 75007 Paris. Before becoming one of the city's most iconic green spaces, the site was occupied by farmland. In the 18th century, it was transformed into a military drill ground for the students of the École Militaire, from which it takes its name, inspired by Mars, the Roman god of war.

Although originally under military control, the Champ de Mars soon became a venue for major public gatherings. In 1780, it hosted a renowned horse race between the chief riding master of the École Militaire and the Prince of Nassau. During the French Revolution, it became an important setting for national celebrations, including the Festival of the Federation in 1790. It also witnessed more tragic events, most notably the Champ de Mars Massacre of July 17, 1791. Jean-Sylvain Bailly, then Mayor of Paris, was later held responsible for the incident and was executed during the Reign of Terror. Over the centuries, the Champ de Mars has remained a popular site for celebrations, commemorations, and major public events.
