I here group pictures of a building at the southern end of the ridge, together with some pictures taken from there. The towers and walls continue for a stretch along the west side further, I called them the "southern walls" for the time being. I include pictures taken from the terrain at the building looking to the other, northern side of the terrain. In between the two are some buildings and a gate that I use the term "middle" for.
I will rename pictures shortly, then the terms I used will be visible.
