Museo dell'Opera del Duomo

This museum holds the actual treasures that once adorned Florence's cathedral complex, moved here for protection from weather and theft. You'll see Michelangelo's unfinished Pietà (his last work, which he smashed in frustration), Ghiberti's original Paradise Doors from the Baptistery, and Donatello's haunting wooden Mary Magdalene. The collection spans 700 years of cathedral art, including the original facade statues and medieval tools used to build Brunelleschi's dome.

The experience flows chronologically through three floors of sleek, climate controlled galleries that put most Italian museums to shame. The ground floor centers around Ghiberti's gleaming bronze panels, displayed at eye level where you can study every biblical scene up close. Upstairs, you'll face Michelangelo's towering Pietà in a darkened room that feels almost sacred. The medieval section showcases massive stone prophets by Donatello and Andrea Pisano that once stared down from the cathedral's exterior.

Most visitors rush through in an hour, but you need at least two to appreciate the craftsmanship. Skip the basement's architectural fragments unless you're an engineer. The €18 ticket includes the cathedral complex, making it decent value, but the museum alone justifies the cost. Come early when tour groups haven't arrived yet.
