Where was that Upper Room?
The room is also known as the Cenacle (which means "dining room"). Scripture scholars believe it was the second floor of a synagogue (a Byzantine church was later constructed on its remains) located on Mount Zion.
Since the fourth century, the site has also been thought to be the room where the Last Supper took place.
During the destruction of Jerusalem in 70 AD, the room was spared any damage and soon became known as the Church of the Apostles. That church was later torn down and replaced by a new church in 382, which itself was destroyed nearly 300 years later when the Persians invaded Jerusalem. Crusaders built the present church in the 12th century. The structure retains portions of the original walls.
The first floor of the Cenacle is also believed to contain King David's burial place.
In 1335, the site belonged to the Franciscans, but it was taken away by the Ottomans in 1548. In 1948, the site came under control of Israel. Currently, Christians are allowed to pray at the Cenacle, but no official Masses are permitted.
