Science and telescopes almost cost Galileo a Christian funeral. His head finally found rest beneath a tombstone in this Franciscan Basilica.

His ghost’s in good company (Rossini, Machiavelli) – and there’s nary a more stunning cathedral in which to spend eternity. View Donatello’s handiwork (the Crucifix and gilded Annunciation) as well as myriads from other masters.
