St. Peter's Basilica Dome History
The original architect of St. Peter's Basilica, Bramante, drew inspiration from the magnificent Pantheon when designing the structure. He envisioned a St Peter's Basilica dome that would share a similar profile, albeit with a unique lantern. To achieve this, Bramante proposed transforming the supporting wall into a raised drum supported by four piers. The wall would be made lighter by incorporating windows and a peristyle, adding grace and luminosity to the design.
After Bramante, Sangallo took over the project in 1513 and drew inspiration not only from the Pantheon but also from the Florence Cathedral. Sangallo's contributions further enriched the architectural vision of St. Peter's Basilica, combining elements from these notable structures to create a truly remarkable masterpiece.
When Michelangelo assumed the role of architect for the Basilica, he embarked on a remarkable redesign of the St. Peter's Basilica dome. Drawing inspiration from the previous designs, he infused his own artistic vision to create a dome that was both realistic and awe-inspiring. His ingenious plan involved constructing the dome with two layers of brick, elevating it from piers on a drum. In Michelangelo's rendition, the peristyle and arcaded elements were replaced by an arrangement of 16 pairs of Corinthian columns, skillfully interconnected by arches. This ingenious design choice bestowed the dome with a captivating ovoid shape, adding to its grandeur and magnificence
Giacomo della Porta and Domenico Fontana were entrusted with the task of finalizing the construction of the dome, which they successfully accomplished in 1590. Their efforts were made under the patronage of Pope Sixtus V, who appointed them for this significant undertaking. Fontana, in particular, took charge of completing the lantern atop the St. Peter's Basilica dome.
To commemorate the achievements of Pope Sixtus V, an inscription was added during the reign of Gregory XIV. It served as a tribute to the pontiff's contributions to the completion of the dome. However, in the subsequent papacy of Clement VIII, the cross was raised in place of the inscription, symbolizing the reverence and religious significance associated with St. Peter's Basilica.
Mosaics on the Dome

The mosaics on St. Peter's Basilica Dome were a collaborative effort of numerous artists. In the late 16th century, Giovanni de' Vecchi and Cesare Nebbia adorned the dome's pediments, portraying the four Evangelists, while Cesare Roncalli crafted upper triangle angels. Popes and Saints were rendered by Giovanni Guerra and Cesare Nebbia; Cristoforo Pomarancio designed motifs between 16 ribs.
Clement VIII commissioned Giuseppe Cesari, the Cavalier d'Arpino, to embellish the dome's upper section. From 1603 to 1612, he formulated the iconographic design and 65 life-sized cartoons. These were translated into mosaic by various artists of the era (Turchi, Torelli, Rossetti, Abatini, Serafini).
Climbing The Dome
To reach the first level of the dome, you have the option of climbing 231 steps or taking the elevator. Once inside Michelangelo's dome, you can admire the breath-taking interiors of the basilica from above, closely examine the intricate mosaics, and explore the roof where statues of Jesus and the apostles are visible from the square below. The roof also offers a gift shop, refreshment stand, and restroom facilities for your convenience. It's a rewarding experience that combines panoramic views, cultural exploration, and a chance to relax and refuel.
While the previous section offers an optional ascent, reaching the absolute top of the St. Peter's Basilica's dome requires climbing an additional 320 steps. However, this part of the climb can be challenging. The single-file staircase spirals upward, and the roof gradually slopes inward as you ascend. As you progress, the staircase narrows, and towards the end, you will rely solely on a rope for support. It's important to note that this final stretch demands caution and physical dexterity
