The initial structure of the basilica was erected by Emperor Constantine in the 4th century. Positioned over what is believed to be the burial site of St. Peter, the first pope, this ancient edifice saw numerous modifications over time. It began as a monumental shrine to honor the apostle and housed an increasing number of pilgrims arriving in Rome to venerate the tomb.
In the early 15th century, due to structural concerns over the Old St. Peter's Basilica, Pope Nicholas V envisioned a new church. This vision was brought to life by successive popes and architects such as Donato Bramante, who designed a novel central plan inspired by the Pantheon. Bramante's plan was embraced and expanded upon by other eminent Renaissance architects including Raphael and Antonio da Sangallo the Younger.
Michelangelo, taking charge of construction in 1547, maintained Bramante's original central plan while transforming the dome's design. After Michelangelo's passing, the project continued under the guidance of Giacomo della Porta and Domenico Fontana, finalizing the iconic dome. Later, under the direction of Carlo Maderno, the basilica shifted to adopt a Latin cross structure, extending the nave and defining its grandiose approach.
St. Peter's Basilica is adorned with works by some of the most renowned artists of High Renaissance and Baroque periods. Gian Lorenzo Bernini contributed significantly, crafting the Baldachin over the papal altar and the Cathedra Petri, an opulent throne enshrining St. Peter's chair. The basilica's interior is also embellished with a wealth of sculptures and mosaics, capturing religious narratives and the visages of saints.
As a UNESCO World Heritage Site and a living place of worship, continuous efforts are made to restore and preserve St. Peter's Basilica. Restorations protect the fabric of the building and the art it houses from the wear of time and environmental elements. The Vatican oversees these activities, ensuring the site's historical and religious legacy endures for future generations.
St. Peter's Basilica vast interior houses numerous masterpieces of Renaissance art. At the core of the basilica lies the Baldachin, a magnificent high altar designed by Gian Lorenzo Bernini, situated directly above St. Peter’s tomb. Encircling the altar is the Cathedra Petri or "Throne of St. Peter", which symbolizes the unbroken line of the papacy. The experience of visiting St. Peter's Basilica is further augmented through the basilica's architecture and the significance of the main altar, beneath which lies the tomb of St. Peter, a poignant site for many.

Michelangelo's design for St. Peter's Basilica's dome marked a Renaissance architectural triumph, blending Christian symbolism with human ingenuity. His innovative design, which was a departure from the original plans, introduced a complex, large-scale dome that was both a technical marvel and an artistic statement. After his death, Giacomo della Porta continued Michelangelo's work, modifying it to include a more pointed shape for enhanced stability, while honoring the original vision. Completed in 1590, the dome, standing at about 136 meters, remains a prominent feature of Rome's skyline, the dome symbolizes both the heavenly aspirations of the Catholic Church and the unparalleled heights of artistic and architectural endeavor.
The interior of the St. Peter’s Basilica dome is adorned with intricate frescoes and stucco decorations that draw the eyes of visitors upward. The most prominent Latin inscription, visible from the floor of the basilica, is "You are Peter, and on this rock I will build my church, and I will give you the keys to the kingdom of heaven." This statement, attributed to Christ speaking to Saint Peter, underscores the spiritual authority of the Papacy and the Vatican's foundational role in the Christian world. The use of mosaics for these inscriptions, rather than painted frescoes, ensures their longevity. The dome’s oculus, a remarkable engineering feat, allows natural light into the basilica’s grand interior, creating an atmosphere of ethereal beauty.
You can visit the dome with a separate ticket from the basilica entrance, which can be acquired on-site.
There are two options for reaching the top. The first involves taking an elevator to the roof level and then climbing 320 steps to the top. The second, less expensive option requires visitors to climb all 551 steps on foot. The stairway is narrow and can be quite strenuous, making it not easily accessible. The dome is exposed to the elements, so the experience can vary depending on the weather – on hot days, the climb can be particularly challenging, so carry water and wear sun protection and on rainy and windy days, the dome might be less crowded, offering a different experience.
