The origin of the name of the town is unknown. The local tradition attributes it to Theuderic IV, the penultimate Merovingian king, who was imprisoned by Charles Martel, without a reliable source. Château-Thierry is the birthplace of Jean de La Fontaine and was the location of the First Battle of the Marne and Second Battle of the Marne. The region of Château-Thierry (the arrondissement, to be exact) is called the country of Omois. Château-Thierry is one of 64 French towns to have received the Legion of Honour.

In the late years of the western Roman empire, a small town called Otmus was settled on a site where the Soissons-Troyes road crossed the Marne river. During the 8th century, Charles Martel kept king Theuderic IV prisoner in the castle of Otmus. At this time, the town took the name of Castrum Theodorici, later transformed in Château-Thierry (Castle of Thierry, Thierry is the French or early Roman language translation of Theuderic).

In 946, the castle of Château-Thierry was the home of Herbert le-Vieux, Count of Omois of the House of Vermandois and Soissons.[2]

Château-Thierry was the site of two important battles: the Battle of Château-Thierry (1814) in the Napoleonic Wars between France and Prussia, and the Battle of Château-Thierry (1918) in World War I between the United States and Germany.[3]

In 1918, a mounting for the Paris Gun was found near the castle, though the cannon itself had apparently been moved prior to the emplacement's discovery.[4]


Château-Thierry is situated on the river Marne, at 90 kilometres (56 mi) from Paris.



Château-Thierry station is the terminus station of a regional railway line starting from the Gare de l'Est in Paris. Furthermore, it has rail connections to Châlons-en-Champagne, Nancy and Strasbourg. It is also one of the exits of the A4 autoroute that links Paris with the east part of France. Transval operates the local bus routes.[5]


Château-Thierry was the birthplace of Jean de La Fontaine.
