TGV station exterior location.
The Filming Locations correctly identified "Gare TGV d'Avignon, Vaucluse, France" as "(last train station where he gets off)".
I always thought that was only the interior. The view from Google Earth Street View shows a different exterior. However, the GE Street View from the opposite side, the north side, not as easy to see, matches the exterior as seen in the movie.
So it's one of the rare instances where a location serves as both interior and exterior.
