Jerusalem’s Zion Gate connects the Old City to Mount Zion, just west of the Mount of Olives, and a place that holds sites sacred to Christians and Jews. The Tomb of King David is located here, as is the Room of the Last Supper, a Romanesque Crusader structure also called The Coenaculum.
Also on Mount Zion is Dormition Abbey, which by Catholic tradition where the Virgin Mary fell into eternal sleep (Assumption of Mary).
Keep in mind: When visiting King David’s Tomb, you’ll be asked to switch off your cellphones. And if despite the warning you keep yours on, chances are good you will lose the signal as you approach the tomb. No logical explanation.
