Hello. I am currently writing about Paris and I was wondering what should I do with the names. The Louvre and the Eiffel Tower I wrote in English, since they are so very famous, but I was writing Jardin des Tuileries, Avenue des Champs-Élysées and some other landmarks in french so as to leave some french ambient in the book. It doesn't seem right to write Eiffel and Louvre in English and the others in French. Should I write all of them in English or French (I prefer French then), or can I write the names of landmarks in two languages? Thank you.
