From here you can see just the roof of the theological school for boys (just to our right of the man walking up the path). This is a descendent of the famous Patmain school that flourished in the late stages of Turkish occupation. Skala clusters at the left end of the harbor. Upper Kampos can be seen (barely) above Skala (take a 45 degree line up and to the right from the man on the path).
Note the cruise ship in the outer harbor. Boats that size cannot dock in the harbor proper, and instead ferry their passengers back and forth in smaller boats.
