Siena Cathedral (Italian: Duomo di Siena) is a medieval church in Siena, Italy, dedicated from its earliest days as a Roman Catholic Marian church, and now dedicated to the Assumption of Mary. It was the episcopal seat of the Diocese of Siena, and from the 15th century that of the Archdiocese of Siena. It is now the seat of the Archdiocese of Siena-Colle di Val d'Elsa-Montalcino. The cathedral was designed and completed between 1215 and 1263 on the site of an earlier structure. It has the form of a Latin cross with a slightly projecting transept, a dome and a bell tower. The dome rises from a hexagonal base with supporting columns. The dome was completed in 1264. The lantern atop the dome was added by Gian Lorenzo Bernini. The bell tower has six bells, where the oldest one was cast in 1149. The nave is separated from the two aisles by semicircular arches. The exterior and interior are constructed of white and greenish-black marble in alternating stripes, with the addition of red marble on the façade. Black and white are the symbolic colors of Siena, etiologically linked to black and white horses of the legendary city's founders, Senius and Aschius. There are thirty-five statues of prophets and patriarchs grouped around the virgin. The finest Italian artists of that era completed works in the cathedral. These artists were Nicola and Giovanni Pisano, Donatello, Pinturicchio, Lorenzo Ghiberti, and Bernini.

The Siena Cathedral Pulpit is an octagonal structure in Siena Cathedral sculpted by Nicola Pisano and his assistants Arnolfo di Cambio, Lapo di Ricevuto, and Nicolas' son Giovanni Pisano between the fall of 1265 and the fall of 1268. The pulpit, with its seven narrative panels and nine decorative columns carved out of Carrara marble, showcases Nicola Pisano's talent for integrating classical themes into Christian traditions, making both Nicola Pisano and the Siena pulpit forerunners of the classical revival of the Italian Renaissance.

The Battistero di San Giovanni (Italian: "Baptistry of St. John") is a religious building in Siena, Italy. It is in the square with the same name, near the final spans of the choir of the city's cathedral. It was built between 1316 and 1325 by Camaino di Crescentino, the father of Tino di Camaino. The façade, in Gothic style, is unfinished in the upper part, such as the apse of the cathedral. In the interior, the rectangular hall, divided into a nave and two aisles by two columns, contains a hexagonal baptismal font in bronze, marble and vitreous enamel, realized in 1417-1431 by the main sculptors of the time: Donatello (panel of "Herod's Banquet" and statues of the "Faith" and "Hope"), Lorenzo Ghiberti, Giovanni di Turino, Goro di Neroccio and Jacopo della Quercia (statue of John the Baptist and other figures). The panels represent the Life of John the Baptist, and include: "Annunciation to Zacharias" by Jacopo della Quercia (1428-1429) "Birth of John the Baptist" by Giovanni di Turino (1427) "Baptist Preaching" by Giovanni di Turino (1427) "Baptism of Christ" by Ghiberti (1427) "Arrest of John the Baptist" by Ghiberti and Giuliano di Ser Andrea "The Feast of Herod" by Donatello (1427)These panels are flanked on the corners by six figures, two by Donatello ("Faith" and "Hope") in 1429; three by Giovanni di Turino ("Justice", "Charity" and "Providence", 1431); and the "Fortitude" is by Goro di Ser Neroccio (1431).The marble shrine on the font was designed by Jacopo della Quercia between 1427 and 1429. The five "Prophets" in the niches and the marble statuette of "John the Baptist" at the top are equally by his hand. Two of the bronze angels are by Donatello, three by Giovanni di Turino (the sixth is by an unknown artist). The frescoes are by Vecchietta and his school (1447-1450, Articles of Faith, Prophets and Sibyls), Benvenuto di Giovanni, the school of Jacopo della Quercia e, perhaps, one by Piero Orioli. Vecchietta also painted two scenes on the wall of the apse, representing the Flagellation and the Road to Calvary. Michele di Matteo da Bologna painted in 1477 the frescoes on the vault of the apse.
