I would have loved to have seen the last supper, etc, but we flew out of Milan and came from visiting family in Santa Giuletta in the country, went to Mass in the Cathedral of Milan but didn't have time to go to Santa Maria.
Seeing the sistine chapel was pretty wonderful. I really liked a lot of the Michaelangelo, but I was more impressed with some other artists. Seeing the Berninis in Rome was pretty incredible, and we saw a ton of Giotto including all the work he did in the Basilica of St. Francis in Assisi, and the Scrovegni Chapel. Another standout was the works or Signorelli in the Orvieto Cathedral, another last judgement piece.
