You will find as many noteworthy sculptures inside the cathedral. Among them is the darkened statue of St. John the Baptist in bronze by the Renaissance sculptor Donatello which is kept in the eponymous Chapel of St. John the Baptist. The Angel Candleholders by Domenico Beccafumi near the altar and Wall Tomb of Tommaso Piccolomini near the bell tower entrance are must-see sculptures. In the left transept, you can find artifacts such as the Tomb of Cardinal Riccardo Petroni, which features four figures carrying a stone sarcophagus. The detailed holy water stoups by Antonio Federighi that sit at the entrance of the Cathedral are also skillfully carved stone artifacts to be admired.
