What is "chalons-en-champagne"

Châlons-en-Champagne ( or [ʃɑ.lɔ̃.ɑ̃.ʃɑ̃.paɲ]) is a city in France. It is the capital of both the department of Marne and the region of Champagne-Ardenne, 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.
