Tintin and France

Recently I am looking for the French things that Hergé adopted. What I found were the Marlinspike hall, a small house in Nyon and the place, Saint-Nazaire.
Are they all? Has anyone done research like this before?
Could you please kindly tell me your discoveries?

Thank you! :-)

Err... Nyon (and Rolle) are Swiss towns, on the northern shore of Lake Geneva.

About French 'things' (I love that word):
1. At the end of King Ottokar's Sceptre, Tintin flies back from Douma to Marseilles, a harbour in the South of France;
2. The Eiffel tower is searched by the Thom(p)sons at the end of Prisoners of the Sun, and you can see Paris at its feet.

That's about all, imho...

Ahh, seems that I forgot the famous Eiffel Tower!

Yamilah, thanks for your help; my geography is not very good...!
