text: Châlons-en-Champagne () is a city in the Grand Est region of France. It is the capital of the department of Marne, despite being only a quarter the size of the city of Reims.
  Formerly called Châlons-sur-Marne, the city was officially renamed in 1998. It should not be confused with the Burgundian town of Chalon-sur-Saône.
  History
  The city was a Gallic and later a Gallo-Roman settlement known in Latin as Catalaunum, taking its name from the Catalauni, a Belgic tribe dwelling in the region of modern Champagne.
  Châlons is conjectured to be the site of several battles including the Battle of Châlons fought in 274 between Roman Emperor Aurelian and Emperor Tetricus I of the Gallic Empire. The Catalaunian Fields was the site of the battle of Châlons in 451 which turned back the westward advance of Attila.
