This is Chateau de Walzin, which I've photographed before from the same angle in the winter. I wanted to get here for the fall colors, I was probably one week late for the best color but at least I got good light!
The third image is just a phone snap, but shows that getting to the best viewpoint is actually a bit tricky (in fact, if I hadn't been there before, I probably wouldn't have dared to scramble down).
