Photo: The East Wall

It doesn't really look that imposing from this angle but the walls are built atop 300 foot cliffs. Anyone foolish enough to attack from this side would be exhausted by the time they reached the base of the walls.

Though I didn't like the light from this angle, I couldn't resist this shot of the serpentine wall as it hugged the top of the ridge. My one mistake, not rotating the polarizer when I rotated the camera 90 degrees.
