The Last Supper Room or Coenaculum:

Commemorated as the "upper room" in which Jesus had the Last Supper with his disciples; later the event of pentecost also took place here. It is located directly above the Tomb of David. The present "Last Supper Room," was built in the 12th century, but the foundations go back to at least the 2nd century AD. I couldnt visit the tomb of David as it was Shabbat and so did not go...
