Eight key figures from backgrounds as different as they are complementary: architect Jean-Michel Wilmotte, historian Boris Bove, demographer Hervé Le Bras, filmmaker Cédric Klapisch, mayor Célestine Ketcha-Courtès, ethnologist Anne Monjaret, artist Magda Danysz and industrialist Antoine Frérot, can be found in this book, linked by the city and its present, past and future worlds. The book links the perspectives of these 8 personalities about the world to come through their streets and points of view.
