Cenacle

The Cenacle (from Latin cenaculum), also known as the "Upper Room", is a room in Jerusalem traditionally held to be the site of The Last Supper. The word is a derivative of the Latin word cena, which means dinner. In Christian tradition, based on Acts 1:13, the "Upper Room" was not only the site of the Last Supper (i.e. the Cenacle), but the usual place where the Apostles stayed in Jerusalem, and according to the Catholic Encyclopedia^[2] "the first Christian church".
