Fascinating Facts About Siena Cathedral

- A major expansion in the 14th century would have made it one of the largest churches in Europe — but the Black Death of 1348 stopped construction. The unfinished walls, now part of the Panorama, remain a must-see.
- The Duomo’s black and white marble symbolizes Siena’s historic coat of arms.
- Renaissance legends like Giovanni Pisano, Michelangelo, Donatello, and Gian Lorenzo Bernini created sculptures and artworks that still amaze visitors today.
