Dome of the Rock, it’s there in the picture to put in perspective where you’re looking. The City of David is everything down from the City Walls. At the bottom of the stairs are the Pools of Siloam. Christ put mud on a blind mans eyes Joh. 9:7. People would first stop at the pools to wash and purify themselves and then from there take the long grand staircase (long line that goes up through the entire picture beginning at the pool at the bottom) that went all the way up to the temple.
Dome of the rock in Eastern Jerusalem is a place I used to love to go to due to my religious characteristics. For those who don't know, the dome of the rock is a century rock that us Muslims believe Muhammad was sent to heaven from.
