Santa Croce in Florence—
you can't talk about this basilica without
doing some serious name-dropping:
Founded by St. Francis himself, it's the
largest Franciscan church in the world;
builders included di Cambio,
Vasari, and Brunelleschi; frescoes by Giotto;
tombs (or funerary monuments) for
Dante, Galileo, Gentile, Ghiberti, Machiavelli,
Michelangelo, Rossini, Marconi, and Fermi.
See what I mean?
