Champagne-Ardenne was a region in northeastern France, but as of 2016, it was merged with the neighboring regions of Alsace and Lorraine to form the new region of Grand Est. However, I can provide you with a list of some of the major cities and towns that were part of the Champagne-Ardenne region prior to the merger:
- Reims – The largest city in the region and famous for its historic cathedral, where French kings were traditionally crowned.
- Troyes – A historic town known for its well-preserved medieval architecture.
- Châlons-en-Champagne – Another significant city in the region with a rich history.
- Charleville-Mézières – A city known for its cultural events and the birthplace of the poet Arthur Rimbaud.
- Épernay – Renowned for its champagne production and home to many famous champagne houses.
- Saint-Dizier – A town with a mix of industrial and historical aspects.
- Sedan – Famous for its massive Château de Sedan, one of the largest fortified castles in Europe.
- Vitry-le-François – A town situated on the Marne River.
- Laon – Although it’s now part of the Hauts-de-France region, Laon was historically associated with Champagne-Ardenne.
