The same problem we have here, on our hill. Years ago, it was possible to hike everywhere, to pick up herbs, to enjoy the wild life. Now, we can't climb the hills because there are fences everywhere.
Thinking about this excursion, I wanted to show you how was the life in a castel.
Castels could control the territory where not so many obstacles as in modern times. All the strip of the beach was clearly visible for kilometers (I measured once that the seaside of Salerno is about 6 or 7 km's long. And it's possible to see much more from the castel.
Internal rooms were not less protective. In fact, more clever governors used such fortifications as prisons -castel of Salerno, too.
That is why, prisoners of all times applyed to the Saints for protection (picture on the wall of the castel of Salerno applying to the S.Leonard and S. Catherine)
