On the north wall is The Last Supper, the unrivalled masterpiece painted between 1495 and 1497 by Leonardo da Vinci, whose work was to herald a new era in the history of art. The representation by Leonardo da Vinci depicted the moment immediately after Christ said, “One of you will betray me”. Unfortunately, Leonardo did not work in fresco but in tempera on a two-layered surface of plaster that did not absorb paint. The Last Supper, which Leonardo da Vinci painted in the refectory of the Dominican convent of Santa Maria delle Grazie, is undisputedly one of the world’s masterpieces of painting. IntegrityThe property contains all the elements that express its unique value, especially the Santa Maria delle Grazie complex, formed by the church, the convent and the Last Supper painted by Leonardo da Vinci.
