Mount Zion, the hill immediately southwest of the walls of the Old City of Jerusalem, carries in a single Crusader-era building two of the most sensitive shrines in the city, stacked one above the other.
The name that migrated
The name Zion first attached, in the Hebrew Bible, to the ridge to the east, the original city of David and site of the Temple, and came only later, in Jewish and Christian tradition, to be applied to this southwestern hill. The migration of the name is itself a lesson in how sacred geography shifts; the hill now called Mount Zion is not the biblical Zion of the earliest texts.
The Cenacle and the Tomb of David
Two shrines share one structure on the crest. On the upper floor is the Cenacle, the room where Christians hold that Jesus ate the Last Supper with his disciples and where the Holy Spirit descended at Pentecost, making it, in Christian memory, the birthplace of the Church. Immediately below it is a cenotaph venerated by Jews as the Tomb of King David, a tradition that grew up in the medieval period. Nearby stands the Benedictine Dormition Abbey, marking where tradition says Mary fell asleep in death.
A point of friction
The arrangement, a Jewish holy place directly beneath a Christian one in a building that also carries Muslim history, having served as a mosque, has made the site a recurring point of tension, with control and rights of worship disputed among the communities that revere it. It remains an active place of devotion for Jews at the Tomb of David and for Christians at the Cenacle, its layered claims a compact image of Jerusalem's wider contests.
