The 100 French départements are divided into 342
arrondissements.
The capital of an arrondissement is called sous-préfecture. When an arrondissement contains the préfecture (capital) of the département, that préfecture is the capital of the arrondissement, acting both as a préfecture and as a sous-préfecture.
Arrondissements are further divided into cantons and communes.
The cities of Paris, Lyon and Marseille are also divided into municipal arrondissements, not to be confused with the arrondissements dealt with in this article.
