Moments from Santa Maria delle Grazie

Leonardo da Vinci painted The Last Supper directly onto the refectory wall of this Dominican convent between 1495 and 1498, and almost immediately made a technical decision that would haunt the painting for the next five centuries: rather than using true fresco technique, which requires working quickly into wet plaster and would have limited his ability to revise and layer detail slowly, he experimented with a tempera and oil mixture applied to dry plaster, a method that let him work at his own pace but that began flaking and deteriorating within his own lifetime. What survives today, after numerous restoration campaigns, the most significant completed in 1999, is a painting that scholars still debate how much of is genuinely Leonardo's original hand versus centuries of careful reconstruction.

Access is unusually strict even by the standards of famous artworks: visitors are admitted in small timed groups, roughly fifteen at a time, for exactly fifteen minutes, after passing through a climate-controlled decompression chamber designed to stabilize humidity and dust before you enter the room itself. Book tickets weeks or, in high season, months in advance, walk-up access essentially does not exist. Use your limited time looking at the composition's mathematical structure, the vanishing point of the room's perspective converges precisely on Christ's head, before getting absorbed in any single apostle's individual reaction to the news of the betrayal.
