Travel is doubtless a matter of place, places dreamed-of and imagined, inhabited and frequented. It is one of the modes humans have invented for moving between registers: from dream to reality, daily life to extraordinary occurrence. Putting such representations into perspective, contrasting a place as it appears today with how it looked fifty years ago, or other comparable places around the world, connecting this place with the practices that evolve there: these are only some of the thought experiments Rémy Knafou and his team of researchers indulge in multiple locales, symbols of the practices unique to travel.
