The room of the Last Supper has many names, include this Cenacle and the Upper Room. Cenacle comes from the Latin cena, supper, and the Upper Room is a reference to the fact that it is part of a building with lower floors, of which the lowest is now claimed to be the tomb of King David. The Cenacle has a long history of being destroyed and rebuilt by the different factions who attribute holiness to the site. It was described as the first Christian church and also served as a synagogue during the Ottoman period. The site is associated not only with the Last Supper but is said to be the location of many events mentioned in the New Testament, including the Washing of the Feet, some resurrection appearances, and the fathering of the disciples after the Ascension of Jesus. According to Christian tradition, this was the site that Jesus and the disciples would often stay in while visiting Jerusalem.
The architecture of the room is a fusion of the different rulers who added their own styles over the last 2 millennia. From the Romans to the Persians, every great empire has controlled Jerusalem at one time or another. Currently, the building is divided with pillars and archways, covered with intricate designs. Scholars disagree on the origins of the building and its current architecture.
The Last Supper was an important event in the New Testament narrative, where Jesus predicted his own death and the betrayal of one of the apostles. He proclaimed that the bread they were eating, which would have been matzah, was his body and that the wine they were drinking was his blood. Christians still practice Communion to remember this, and some sects take this literally. This was the last time that the group ate together before Jesus was arrested and crucified. Pilgrims come from all over the world to pay homage to this moment and stand in the same room where this significant event took place.
