Skip-the-line entrance tickets grant access to the museum along with the adjacent cathedral, crypt, baptistry (Battistero di San Giovanni), and Piccolomini Library (frescoed by Pinturicchio). Explore the museum and cathedral complex as part of a city walking tour or on a day trip from Florence to Siena, Pisa, and San Gimignano. Inside the museum, highlights include the 13th-century sculptures by Giovanni Pisano, an early-14th-century altarpiece and stained-glass window by Duccio di Buoninsegna, and works by Donatello and Pietro Lorenzetti.
