Right in the heart of Piazza del Duomo, you'll find the breathtaking Gates of Paradise. These aren't just any doors; they're a pivotal piece of Renaissance art, so beautiful that Michelangelo himself gave them their name. What you'll see on the Baptistery are stunning replicas, allowing you to appreciate the incredible detail of the Old Testament scenes up close. For a deeper dive, the original gilded panels, restored to their full glory, are held just steps away in the Museo dell'Opera del Duomo.
