While you may not have heard of Calascio, you have very likely seen its famous Castle (Rocca Calascio) many times in movies. Probably most famous is its appearance in the movie Ladyhawk, and more recently in the Name of the Rose, and of course many many promotional videos encouraging you to visit Italy.

Getting up to the castle will involve some walking. Unlike American historical places, you will not be able to drive up to within a hundred yards and find a parking lot. In fact, there is not a parking lot at all.
You will first drive to Calscio, winding ever upward on the mountain switchback with stunning vistas all along the way.
When you arrive at Calascio you will want to think about parking when you get to this point where the road branches off to Castel del Monte. From the view on the link, the road that is going up (There are some barricades in the picture) is the one you want to take.
