I first tried to find a path that would get to each position found according to the direction where Lupin was heading. I didn’t notice anything special except that it’s like a circle shape. I tried to find the center of the 6 locations, but the Fontaine des Bois, Parcs et Jardins wasn’t the flag. I then tried to “finish” the circle shape of the path and obtain this:
By zooming to the point near the center,we find the grave of Frédéric Chopin. The flag was 404CTF{tombe_frédéric_chopin}
