How did they get up there?
We kept walking with our backs to the blistering sun. Every time we came to a turn on the path around the walls I expected to see a gate. Instead it seemed we were walking deeper and deeper into what was once a moat surrounding the fortifications. Finally the moat widened and we could see other people in the distance walking between two towers into the city. As we got closer we realized that they were above us on this bridge. I was about to suggest we turn around when out of the corner of my eye I saw a small stairway leading up to the entrance gate.
