Paris Arrondissements Map
The city of Paris itself is officially divided into 20 districts called arrondissements, numbered from 1 to 20 in a clockwise spiral from the centre of the city (which is known as Kilometre Zero and is located at the front of Notre Dame). Arrondissements are named according to their number. You might, for example, stay in the "5th", which would be written as 5e in French.
The very best map you can get for Paris is called "Paris Pratique par Arrondissement" which you can buy for about €3-5 at any news stand. It makes navigating the city easy: so much that one can imagine that the introduction of such map-books might be part of what made the arrondissement concept so popular in the first place. The various tourist information centres and hotels in Paris also provide various city and metro maps for free and which have all the necessary details for a tourist.
