Nice photos. AWR, that Transportation Museum facade reminds me of the view from the driver's seat when heading into Porte Maillot in Paris.
This is the Château de Mussegros, a seemingly abandoned manor in the Haute-Normandie region of France:
On the left is a tree-lined drive, which once upon a time might have looked like GSpotter's last photo. I walked up it a bit but I'll have to come back another time to photograph it properly.
In France, many grand properties are abandoned to the elements. I suppose there are more châteaux than people willing to pay for their upkeep. Very special buildings attract enough tourists to cover their costs, but many others are forgotten.
