1. Santa Maria del Fiore Cathedral
The Cathedral of Saint Mary, whose dome is familiar to tourists from postcards and guidebook photos, has long become an iconic landmark and a hallmark of Florence. Like many churches and temples in Italy, Santa Maria del Fiore is a true treasure trove. The magnificent architecture of the building is matched by the grandeur and opulence of its interior decor, as well as the cathedral's artistic gems — Michelangelo's "Pietà" and Donatello's "Mary Magdalene". The observation deck on the cathedral's dome offers a stunning view of Florence.
