The municipal arrondissement
(, ) is a subdivision of the commune
, used in the three largest cities: Paris
. It functions as an even lower administrative division, with its own mayor
. Although usually referred to simply as an "arrondissements", they should not be confused with departmental arrondissements
, which are groupings of communes within one département
There are 45 municipal arrondissements in France: 20 in Paris (see: Arrondissements of Paris
), nine in Lyon (see: Arrondissements of Lyon
), and 16 in Marseille. However, a law in 1987 assigned the 16 arrondissements of Marseille to eight secteurs
("areas"), two arrondissements by secteur
. Thus, in effect, Marseille can be more properly described as being divided into eight secteurs
, the 16 arrondissements having been made hollow units.
- The largest arrondissement is the ninth arrondissement of Marseille: 63.21 km² (24.4 sq. miles, or 15,620 acres), which is 26% of the size of the city of Marseille, and is 60% the size of the city of Paris (including the Bois de Boulogne and Bois de Vincennes). It contains the Luminy Park, which is a protected park and the calanques of Marseille.
- The smallest arrondissement is the second arrondissement of Paris: 0.992 km² (0.383 sq. miles, or 245 acres).
