What is the wealthiest residential district of Paris itself, and which is it's poshest suburb?

Question

Where in and around Paris would you find it's oldest money? Which area when mentioned, imediately would make a native Parisian think of enormous wealth?

Answer 1

I agree with the first two answers. Other wealthy arrondissements: the 7th, the 8th... as a general rule, those closes to the geographic center of the city are the wealthiest (the 16th being an obvious exception), and suburbs west and south of Paris tend to be posher than those to the north and east.

Answer 2

As said above, Auteuil, Neuilly , Passy, outside Paris and 16th arrondissement in Paris. 8th arrondissement would be more wealthy companies and offices.

Answer 3

18th, 19th, 20th arrondissements: where you'll find some very "wealthy" people.  Just mentioning these districts and people have a certain connotation immediately.

Answer 4

16eme arrondissement of Paris itself. Or Neuilly, Auteuil or Passy, three contiguous suburbs. All rich and well-established.
