Leonardo's masterpiece, the Last Supper,one of the world's greatest painted masterpieces occupies the end wall of the previous refectory of the XVth century Domenican Monastery. Painted by Leonardo between 1495 and 1498 portrays the Apostoles seated together with Jesus when Jesus announced that one of them would betray him. The Disciples' emotion transpiresfrom their gestures, mouvements and faces and contrasts with the apparent immobility of Christ who dominates the centre of a rigously symmetrical composition in perfect perspective. The painting was miraculously untouched by the August 1943 bombings which damaged the nearby cloister and part of the church.
