Introduction and Essential Facts

Siena is a medieval Tuscan city whose cobbled streets and luminous squares are considered a UNESCO World Heritage site . Among its treasures is the Battistero di San Giovanni (Baptistery of St John). This guide explores its history, mosaics and frescos, and offers itineraries for visiting Siena and the surrounding countryside. It also introduces Hotel Minerva, a three‑star hotel in the heart of Siena, as the ideal base for exploring the city .

Essential facts:

• Location: Piazza San Giovanni, beneath the apse of the cathedral. Access is via the steps of Piazza San Giovanni .
• Construction: Built between 1316 and 1325, probably designed by master builder Camaino di Crescentino; the façade was begun later in the 14th century .
• Architecture: Gothic style. The lower façade is clad in white marble with three recessed portals; the upper portion remains unfinished in brick. Inside is a rectangular space with three aisles covered by cross‑vaults, located under the last bays of the cathedral choir .
• Decoration: The floor before the portals is decorated with mosaic and inlaid marble depicting the Baptism (1450–1451). The vaults are completely frescoed with a cycle of the Articles of the Creed by Lorenzo di Pietro (Vecchietta) and assistants (1447–1450). The hexagonal Baptismal Font (1417–1431) combines marble, bronze and enamels with reliefs by Jacopo della Quercia (general design) and contributions from Donatello, Lorenzo Ghiberti, Giovanni di Turino and Goro di Neroccio . Donatello’s bronze Virtues (Faith and Hope) flank the font and a statue of St John crowns the canopy .
• Artworks: The vault frescoes depict 12 scenes from the Creed with apostles and prophets . Lunettes show the Miracles of St Anthony by Benvenuto di Giovanni (c. 1460) and a Foot‑washing scene by Pietro degli Orioli (1489) . A triptych with the Madonna, Saints and Stories of St Stephen by Andrea Vanni and Giovanni di Paolo and various Gothic statues from the school of Giovanni Pisano are also present .

History and Architecture of the Baptistery

Built between 1316 and 1325, the Baptistery was part of the large expansion of Siena’s cathedral. Master builder Camaino di Crescentino likely designed it. The structure had to fit beneath the cathedral’s choir, leading to an unusual rectangular plan with three aisles covered by cross‑vaults . The Gothic façade remains unfinished: the lower section is faced in white marble with three deep portals, while the upper portion is brick. This unfinished state symbolises the human journey toward spiritual completion and underscores the Baptistery’s function as gateway to both the Christian faith and the Sienese community . For centuries, every child of Siena — including St Catherine — was baptised here .

Fresco Decoration and Paintings

The Creed Cycle by Vecchietta

Between 1447 and 1450 the painter Lorenzo di Pietro (known as Vecchietta) and his assistants covered the vaults with a cycle illustrating the Articles of the Creed . The twelve triangular vaults depict scenes from the Creation, Annunciation and Pentecost, surrounded by prophets and apostles, demonstrating the artist’s ability to combine narrative clarity with rich colour. In the apse, Vecchietta painted large scenes such as the Assumption, Annunciation, Flagellation and Way to Calvary, with contributions by Matteo di Giovanni .

Additional frescoes and statues

Other decorations include a cycle of Miracles of St Anthony by Benvenuto di Giovanni (c. 1460), a Foot‑washing (Lavanda dei piedi) fresco by Pietro degli Orioli (1489), and an altarpiece with the Madonna and Saints and the Stories of St Stephen by Andrea Vanni and Giovanni di Paolo . Various 14th‑century wooden and marble statues from the school of Giovanni Pisano enrich the interior . These artworks create a didactic environment: the entire interior was designed to educate the faithful through images .

The Renaissance Baptismal Font

The hexagonal Baptismal Font (1417–1431) is one of the earliest Renaissance collaborative masterpieces. The general design and some panels are by Jacopo della Quercia, while other panels were executed by Lorenzo Ghiberti, Donatello, Giovanni di Turino and Goro di Neroccio . Reliefs depict scenes from the life of St John the Baptist and the New Testament, including the Baptism of Christ, the Banquet of Herod (Donatello’s panel using the stiacciato low relief technique), the Birth of the Baptist, The Preaching of John, The Decapitation of the Baptist and the Presentation of the Head of the Baptist to Herodias. Each artist brought his own style: Donatello’s panel is praised for its delicate modelling; Ghiberti’s work reflects international Gothic elegance; della Quercia’s sculptures show robust forms and a dynamic narrative .

The font’s canopy is supported by slender columns and is crowned by a statue of St John by Jacopo della Quercia. Around the base stand six bronze Virtues; Donatello sculpted Faith and Hope, while other artists executed Justice, Charity, Prudence and Fortitude. The font symbolised Siena’s civic identity and artistic rivalry with neighbouring Florence .
