Locations

Does anybody know the real place/surroundings of:

- the trainstation were the movie begins?
As far as I know the village "Vieux-Moutiers" does not exist in reality, but it is near the crossing of the road D71 in 1961 (in the meantime renumbered in D671!)and the traintrack;

- the hotel/chateau in the movie were all the interior shots and balcony shots are taken?
Is it or was it perhaps an museum/chateau, and was it really near the river Marne?

Hope to hear.
