This view of the iconic Jerusalem skyline is a staple to many a postcard vendor. However, panning out a bit outside the Ottoman-era walls reveals two important locations. First is the Temple Mount which today features the Al-Aqsa mosque and the Dome of the Rock. And, across the street from the Temple Mount and slightly beneath the brilliant blue rooftop is the Iron Age City of David—the original Jerusalem. This small mound was protected on all sides from approach, except from the north, where an enemy could approach unseen down the ridgeline. Thus, the Temple Mount not only served as a holy place, but also as fortified protection from hostile forces from the north.
