The Right Bank is generally characterized as a centre of commerce and banking, haute couture, palace hotels, and grand, wide boulevards.
The Left Bank, historically considered the centre of learning and religious activity, and with its enclave of writers and intellectuals, is rich with cafe life. The hotels here tend to be small and charming, rather than grand hotels of luxury.
Paris is divided into 20 districts called arrondissements, each with its own mayor and town hall or "marie".
Many small neighborhoods lie within these arrondissements, several spilling over its boundaries into others. Each arrondissement is referred to by an ordinal number; the first ("le premier"), the second (le deuxieme"), etc. They spiral clockwise from the central portion of the city to the ring road called the Boulevard Peripherique.
The number of the arrondissement is also the last 2 digits of a Paris address, whereas the first 2 digits signify Paris.
For example, an address with a postal code of 75008 will be in the eighth arrondissement; one with a postal code of 75011 will be in the 11th.
This helps when you have an address you need to go to...it'll help you head towards the right part of the city.Each arrondissement has its own unique character and selection of attractions for the traveler:
