Guess Where

Occasionally I sneak a Guess Where" photo (in the side bar) from our French Travels and in the past two photos, regular reader Ladybird has guessed correctly - Both those have been from the Loire. Well Ladybird, I can give you a clue - this one is much closer to Belgium but still in France, not that far from Paris.
Can anyone beat Ladybird this time.
