The St. Peter's Basilica Dome was designed by artist extraordinaire, Michelangelo. Not only does the exterior of this towering dome look impressive, but the interiors are spellbindingly beautiful, adorned with vibrant mosaics and sumptuous stucco ornaments.
The dome’s beauty and history can be overwhelming if you don't know where to look and which section to visit first. For this, we recommend opting for a St. Peter's Basilica Dome guided tour. A guided tour is perfect for visitors who want to do more than just view the architecture and return.
It’s important to note that a standard St. Peter’s Basilica tour does not include access to the Dome; you will have to purchase tickets that specifically offer a tour of the dome.
St. Peter's Basilica Dome TicketsThe dome of St. Peter's Basilica stands above the altar and rises to a total height of 400 feet from the floor. In the four spandrels that connect the square piers and the drum, you will find medallions depicting the four Evangelists: Matthew with the ox, Mark with the lion, Luke with the angel, and John with the eagle.
You will find an inscription featuring the words of Christ to Peter, as recorded in Mathew 16:18: and the letters are illuminated by the light streaming from 16 large windows.
Above this, the dome is divided into sixteen ribs decorated by 96 figures, followed by a star-spangled night sky, on top of which is the lantern. At its base, you will find a Latin inscription that translates to: "To the glory of St. Peter, Pope Sixtus V in the year 1590, the fifth of his pontificate". The 18 m long lantern comes to end with the painting of God.
Architecture of St. Peter's BasilicaAbove the windows that light up the inscription, the dome is divided into sixteen ribs and many segments. Each section is decorated by the portrayal of a majestic figure, across six ascending concentric levels. Starting at the bottom these are the figures you will find through the dome:
1. Busts of the 16 popes buried in the Basilica.
2. Figures of Christ, the Virgin Mary, St. Joseph, St. John the Baptist and the Apostles.
3. In rectangular frames, you will find depictions of angels bearing the instruments of Jesus' Passion.
4. In circular medallion, you will find the depiction of faces of cherubim and seraphim.
5. Above this are angels, the custodians of St. Peter's tomb.
6. Faces of winged angels.
Above these mosaics, you will see the Latin inscription that honors Pope Sixtus V, followed by the lantern, at the center of which you will find the depiction of God.
Many artists are responsible for the mosaics on the St. Peter's Basilica Dome.
Towards the end of the 16th century, Giovanni de' Vecchi and Cesare Nebbia were commissioned to decorate the pediments of the dome. They were responsible for creating the representation of the four Evangelists, while the angels on the upper triangles are designed by Cesare Roncalli. The Popes and Saints were by Giovanni Guerra and Cesare Nebbia; the decorative motifs between the 16 ribs are by Cristoforo Pomarancio.
Clement VIII commissioned Giuseppe Cesari, known as Cavalier d'Arpino to work on the decoration on the upper part of the dome. He prepared the cartoons from 1603 to 1612. He designed the iconographic layout and created 65 life-size cartoons These drawings were transposed into mosaic simultaneously by various mosaic artists of the period (Turchi, Torelli, Rossetti, Abatini, Serafini).

Bramante, the original architect of the St. Peter's Basilica, was inspired by the Pantheon. The dome would follow a similar profile, except for the lantern. The supporting wall would become a drum raised on four piers. The wall would be lightened with the help of windows and a peristyle.
Sangallo, who took over in 1513, found inspiration from the Florence Cathedral as well as the Pantheon. He developed on Bramante's plan and converted the peristyle into a series of arched and ordered openings around the base, with a second such arcade in a tier above the first. The lantern became a massive structure, surrounded by a projecting base, and peristyle. This would have been surmounted by a conical spire.
When Michelangelo took over as the architect of the Basilica, he redesigned the dome. He took inspiration from the existing designs but modified them to a more realistic, but magnificent one. His dome would be made with two shells of brick and would be raised from piers on a drum. The peristyle and arcaded was replaced by 16 pairs of Corinthian columns, connected by an arch, which would give the dome an ovoid shape.
When Michelangelo died in 1564, only the drum of the dome and piers were complete. The work was continued under his assistant Jacopo Barozzi da Vignola with Giorgio Vasari who followed Michelangelo's plans exactly. However, very little progress was made.
The dome was brought to completion by Giacomo della Porta and Domenico Fontana in 1590. They were appointed by Sixtus V. Fontana completed the lantern and had an inscription that would honor Sixtus V during the reign of Gregory XIV. Clement VIII, who followed, had the cross raised in its place.
In the mid-18th century, cracks appeared in the dome, and four iron chains were installed to bind the two shells.
There are two parts to climbing the St. Peter's Basilica Dome.
The first level of the dome is up 231 steps. Sounds exhausting? Well, you can skip the climb and take the elevator. You wind up on the inside of Michelangelo's dome, and from here, you can enjoy the views of the interiors of the basilica from above, explore the mosaics up close, and also explore the roof of the basilica, which houses the statues of Jesus and the apostles that you can see from the square. You can wind down at the roof by shopping at the gift shop and grabbing a snack from the refreshment stand. You will also find a restroom here.
However, it is important to remember at this level, you are simply viewing the dome up-close from the gallery. To reach the inside of the some you will have to climb a small staircase.
This part of the climb is optional. There is no elevator for this part, but climbing the next 320 will take you to the absolute top of the Basilica's dome. However, this part of the climb can be tricky. The single-file staircase spirals up, and the roof tends to slant in as you go up. As you keep climbing the staircase gets narrower, and on the last steps, you will only have a rope to hang on to.
While there are windows along the way, if you are claustrophobic or acrophobic, this climb can prove to be difficult. However, the climb will prove to be worthwhile once you are at the top. You can enjoy spectacular views of the city from here.
The St. Peter's Basilica Dome is open during the following hours:
April to September 7:30 AM to 5 PM
October to March: 7:30 AM to 5 PM
Duration: It can take you about a half-hour to an hour to finish the climb.
