This tours is definitely lacking in visits to the holy places but little church certainly makes up for it.  You walk in here and find some amazing crypts of who is who of Renaissance and beyond.  St. Francis of Assisi left his frok here.  Buried in this church are Galileo, Michelangelo, Dante, Machiavelli, Marconi, Rossini and many others. The Tree of Life is a fresco in the monks’ refectory.   It’s a great please full of treasures.
