The Last Supper Room in Jerusalem is located directly above the Tomb of David, very close to the Zion Gate. It is also known as the Upper Room and the Cenacle. This structure is traditionally held to be the site of The Last Supper, it was was a meeting place for the followers of Jesus. At that time, it was inside the city walls of Jerusalem.
The Mount Zion church was reconstructed in the 4th century after persecutions ended, at which point it was known as “the Upper Church of the Apostles.” The current building dates from the 12th century and is a rectangular room with pillars and a groin-vaulted ceiling.
