Hi Giafranco! I visited the websites that you have mentioned and can understand the position from where you took the shot. I was suspecting from the beginning that it should be some sort of hilltop because the skycrappers in your photograph look small but I never knew that there is castle with rich history.
A great view as if you are on the top of the world and can see rest of the world. I can feel the sensation when somebody goes at such a place. As far as the "50 mm lens problem" is concerned, I have understood well now. So, I won't feel much sorry, if I don't have a small f-number lens. Or should I feel sorry? Am I missing something? Thank you so much for such a nice and informative reply. With best regards, Ayash.
