The painting "the last Supper" was completed in 1498. The story depicts the last supper of Jesus with his disciples at which he announced the betrayal of one of them. The meeting was held secretly. During the meal, an important event took place – the Establishment of the New Covenant and the sacrament. Information about the last supper are found in all the Gospels. "While they were eating, Jesus took bread, and blessed it, and brake it, and gave to them, and said, take, eat; this is My Body. And he took the Cup, gave thanks, gave it to them: and they all drank of it. And he said to them: this is My Blood of the New Testament, which is shed for many".
The mural is striking in its expressiveness and technique. Unfortunately, Leonardo da Vinci executed the fresco paints, which were short-lived. Already fifty years later, the picture has lost its original appearance.
After the flooding of the refectory in the year 1500, as well as several unsuccessful restorations, the fresco was damaged even more. In 1976, after moving through the French Alps, in the room where the mural was organized stables and storage for hay. The last restoration of the frescoes took twenty one years and on 28 may 1999 it was reopened for viewing. Today the fresco "the last Supper" called "the Last supper" is a Masterpiece of World Heritage.
