The Last Supper by Leonardo da Vinci is undoubtedly one of the most iconic, most famous works of art of all times. As such, it has always attracted crowds to the Refectory of the Dominican church of Santa Maria delle Grazie in Milan where it is located.

It is also regarded as a miraculous painting: it survived Leonardo’s own experimentations with a new faulty fresco technique, and subsequently survived rudimentary restorations throughout the centuries; then, during WWII, in August 1943, when allied bombings razed Milan and destroyed the church, this mural amazingly survived intact on the only wall left standing in the refectory.
