The Bible does not give the exact location of the Last Supper. Most scholars believe the event must have taken place either in or around the city of Jerusalem because the New Testament states that the Last Supper occurred a few days after Jesus arrived in that city.
The Last Supper was the final meal that Jesus had with his 12 disciples according to Christian tradition. The gathering was particularly noteworthy because, during the meal, Jesus predicted that one of those present would betray him to the Roman authorities. Jesus also predicted that Peter, one of the leading disciples, would deny knowing him.
