Explore the Inside of Siena Cathedral | Frescoes, Sculputures & More

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.

Most of the Cathedral’s artworks are on display in the museum within the cathedral complex. Works like the cathedral altarpieces like Assumption of the Virgin by Bartolomeo Cesi in 1594 garner significant interest in the art world. The four frescoes in the chancel areas like The Fall of Manna and Esther and Ahasuerus by Ventura Salimbeni in1610 are done in vivid detail. In the apse of the cathedral, behind the altar, you will find the large fresco of Saints and Paradise by Domenico Beccafumi. The large painting in the chancel entitled ‘The Adoration of the Sheperds’ by Alessandro Casolani is considered a masterpiece.

On the left of the nave, you will discover a spectacular stone altar. It was commissioned by Cardinal Francesco Todeschini Piccolomini (Pope Pius III) in the hope that one day become this tomb would become his final resting place. It features a large stone structure of Carrara marble built by Andrea Bregno between 1481 and 1485. Later, between 1501 and 1504 four marvelous niche sculptures of St. Peter, St. Augustine, St. Paul, and St. Gregory were sculpted by Michelangelo and added to the arrangement. In the center of the structure is a Sienese school painting of the Madonna with Child by Paolo di Giovanni Fei.

Near the altar, a stunning pulpit stands mighty before the church pews. It is a raised platform from where sermons are delivered. This particular pulpit is made of Sienese Carrara marble and sculpted by Nicola Pisano between 1265 and 1268. It is supported by columns that begin from a short staircase that leads upwards to the platform. At the bottom of the columns are allegorical figures of lions consuming prey. The platform of the pulpit tells many stories in its intricate engravings. There are seven scenes of the Life of Christ, from his birth to his crucifixion, carved in breathtaking detail.

The Choir consists of wooden choir stalls arranged near the presbytery. The stalls are centuries old and were crafted into complicated designs and wood carvings. There were originally ninety choir stalls out of which 36 remain. Embedded in the backs of the choir stalls are beautiful wooden panels that were accomplished using the technique of marquetry wherein shapes of different types of wood are fitted into each other. They are considered the greatest work to come from Fra Giovanni da Verona who created them between 1456 and 1525.

Situated in the right transept is an enclosed space that is known as the Cappella del Voto. It holds the sacred painting of Madonna del Voto by Dietisalvi di Speme. It is of great importance to the Sienese people. As legend has it, the people of Siena pledged their devotion to Mother Mary in front of this painting before the battle of Montaperti and later triumphed in a clash with the invading Florentine soldiers. On either side of the centerpiece are two masterfully sculpted statues of St. Jerome and St. Mary Magdalen undergoing a mystical experience that were created by Gianlorenzo Bernini.

Above the apse in the presbytery is a large rose window called the Life of Mary by Duccio di Buoninsegna. It contains scenes of the death of Mary, her assumption into heaven, and her coronation. Although what we see now is a copy, the original is a centuries-old work of art and is approximately six meters in diameter. Another spectacular stained glass piece is fitted into the facade of the cathedral. Created by Pastorino de Pastorini in 1549, the piece is a detailed portrayal of the Last Supper of Christ and is an exemplary example of Italian stained glass.
