A model showing the location of early Jerusalem, or the City of David. Notice the steep, rugged Kidron Valley to the right (east). By the days of the New Testament the Central Valley was either filled in or spanned with bridges. Mount Moriah is part of this eastern ridge on which the City of David sits, but is further up the ridge toward the top of the photo (north). Another image of early Jerusalem from the days of Melchizedek (2000 BC) until David (1000 BC).
Early Jerusalem labeled and viewed from the Mount of Olives to the east. Notice the Stepped Stone Structure (Millo).
Mount Moriah to the north of the walls of the City of David. This northern portion of the eastern ridge would be purchased by David from a Jebusite, and Solomon would build the Temple here.
A detailed image of the Stepped Stone Structure with the stronghold/fortress and palace of David on the top inside. The Gihon Springs and their protective towers are below in the Kidron Valley.
