Here is an Overview of the Paris Arrondissements
Paris is divided into 20 arrondissements, or districts. The first one starts in the centre near the Seine and moves in a clockwise circular direction until the 20th arrondissement is reached in the eastern part of Paris. These arrondissements are surrounded by a peripherique, a highway circling Paris.
