St. Peter’s Basilica is the largest church in the world and the spiritual heart of Catholicism—and it sits inside the smallest country on the planet, Vatican City, an independent state nestled within Rome. Entry to the basilica is free, making it one of the most accessible experiences in all of Italy. From the U.S., you can reach Rome with a single layover, and the total flight time runs between 14 and 17 hours; the Vatican is about 2.5 miles from Rome’s historic center, reachable in 20 minutes by metro. The best time to visit is from March to May or September to November—outside the peak summer season, when lines can stretch past two hours. But what surprises most visitors isn’t the sheer size of the place—it’s the sheer number of secrets the Vatican holds about its own popes.
How to get to the Vatican
The Vatican isn’t technically part of Rome, but for all practical purposes, you arrive in the city via Fiumicino Airport (FCO)—the same airport you’d use for any trip to the Italian capital. From the airport to central Rome, the Leonardo Express train reaches Termini Station in 32 minutes (€14; confirm the current price before you travel). From there, Metro Line A takes you to Ottaviano Station in 15 minutes, just a stone’s throw from the Vatican.
Prefer to walk? From Ottaviano Station to St. Peter’s Square is less than a 10-minute stroll. Another popular option is bus 40 or 64, which runs directly from Termini to the Lungotevere, near Castel Sant’Angelo—from there, it’s another 10-minute walk down Via della Conciliazione, the avenue that leads to the square. A taxi from Fiumicino to the Vatican has a fixed fare of around €50 to €60.
The Vatican has been an independent state since the Lateran Treaty was signed in 1929. What separates Rome from the Vatican is, in practice, an invisible border marked by the Leonine Walls, built in the 9th century by Pope Leo IV—you’ll see them as you walk around the state’s perimeter. There’s no passport control to enter; you just pass through a metal detector.
Best time to visit and how long to stay
St. Peter’s Basilica is open every day, and entry is free. As of June 2026, the opening hours are from 7:00 AM to 8:00 PM, with last entry at 7:15 PM—check the official Vatican website before your visit, as hours can change. Outside of July and August—the absolute peak tourist season—the visit flows much more comfortably.
For the basilica alone, set aside 1.5 to 2 hours. If you’re climbing the dome, add another 45 minutes. The Vatican Museums and the Sistine Chapel, which are in the same complex but have a separate entrance and ticket, deserve at least 3 additional hours—it’s better to split them over two days, or you can tackle the whole thing in one day if you’ve got the stamina.
The quietest times are right at opening (before 9:00 AM) and late afternoon, after 4:00 PM. At noon, when tour groups arrive en masse, the basilica gets packed, and the marble acoustics amplify the noise in an uncomfortable way.
The history of St. Peter’s Basilica
The basilica you see today isn’t the original. The first St. Peter’s Church was built in the 4th century by Emperor Constantine on the spot where Christian tradition says the apostle Peter was crucified and buried—on Vatican Hill, then a Roman cemetery on the right bank of the Tiber River. This link between Rome and Christianity is direct: Peter was the first bishop of Rome (what the Church calls the first pope), and his presence in the city marked Rome as the center of Christian faith in the West. Paul, the other great apostle, was also martyred in Rome, and the city became for Catholicism what Jerusalem is for the three Abrahamic religions.
The current basilica was born from a radical decision by Pope Julius II in 1506: to demolish the old Constantinian church and build something unprecedented. The project went through decades of disputes between architects, starting with Donato Bramante, continuing with Raphael Sanzio, and reaching a turning point in 1546 when Michelangelo—who was 71 years old and fundamentally a sculptor—took over the work. It was Michelangelo who designed the iconic dome that defines the Vatican’s skyline. He died in 1564 without seeing it completed; Giacomo della Porta finished the dome in 1590. The final façade, designed by Carlo Maderno, was completed in 1612. The official consecration took place on November 18, 1626—120 years after the first stone was laid.
About Michelangelo and the Sistine Chapel: the story is more complicated than it seems. Michelangelo resisted the commission to paint the Sistine Chapel ceiling, given by the same Pope Julius II—he considered himself a sculptor, not a painter, and feared the project was a public failure planned by rivals to destroy his reputation. He spent four years lying on scaffolding, painting almost entirely alone, and created one of the most studied works in art history. The ban on photography in the Sistine Chapel, in turn, has an economic origin: in the 1980s, the Japanese TV network Nippon Television paid $4.2 million to fund the restoration of the frescoes and received, in return, the exclusive image rights to the restored works. The ban protects that commercial agreement—not the frescoes themselves.
What to see in the Basilica and Vatican
As you enter through the central door of the basilica, the first thing that stops you in your tracks is the scale. The marble floor gleams under a diffuse light coming from the side windows, and the central nave is 187 meters long—the equivalent of two football fields end to end. Marks on the floor show the size of other great cathedrals of the world, all smaller than St. Peter’s.
Michelangelo’s Pietà
To the right as you enter, protected by glass since 1972 (when a disturbed man attacked it with a hammer), is the Pietà—the sculpture of Mary holding the dead body of Jesus, made by Michelangelo between 1498 and 1499, when he was just 24 years old. It’s the only work he ever signed: his name is carved on the sash crossing Mary’s chest. The softness of the marble in the robes contrasts with the hardness of Christ’s ribs in a way that still leaves sculptors speechless today.
Bernini’s Baldachin and the Tomb of St. Peter
In the center of the basilica, under Michelangelo’s dome, rises Gian Lorenzo Bernini’s bronze baldachin—a 29-meter canopy with twisted columns that marks the exact spot where tradition says St. Peter is buried. Below, in the Confessio—the niche lit by 99 perpetually burning lamps—is a golden grate protecting the underground chamber where the apostle’s remains lie.
The Popes Buried in the Basilica
Who is buried in St. Peter’s Basilica? More than 90 popes over the centuries. The Vatican necropolises, accessible by pre-booked guided tour, show the chambers where they rest, from St. Leo I to John Paul II, whose simple white marble tomb draws constant lines of devotees. Pope Benedict XVI is also buried there. Pope Francis broke a tradition of more than 120 years by choosing to be buried at Santa Maria Maggiore in Rome, not in the Vatican—a decision motivated by his devotion to the Salus Populi Romani icon housed in that basilica.
The Dome—and How to Climb It
Climbing Michelangelo’s dome offers a 360° view of Rome that’s hard to beat. The ticket costs €10 for the stairs (551 steps) or €15 with a stretch of elevator up to the drum and the rest on foot—bought inside the basilica itself, or €17/€22 online (2026 prices; confirm on the official website). The most curious part: from an internal gallery at the top of the dome, before you step out onto the terrace, you look down and see the faithful in the nave from a completely different angle—from there, you can read the gigantic mosaic letters that circle the drum, which from the ground look small but are actually 1.4 meters tall each.
What to combine and nearby attractions
The Vatican Museums and the Sistine Chapel are within the Vatican walls, but they have a separate entrance and ticket office from the basilica. The entrance is on Via dei Musei, on the north side of the complex. Book your tickets weeks in advance on the official Vatican Museum website—timed-entry tickets let you skip lines that can reach 3 hours in high season. The difference between the basilica and the Sistine Chapel: they are two distinct complexes, with different entrances and separate routes. You enter the basilica for free from St. Peter’s Square; the Sistine Chapel is accessed through the museums, with a paid ticket. Those taking the museum tour reach the Sistine Chapel at the end of the route.
Castel Sant’Angelo is less than a 10-minute walk from St. Peter’s Square, along the Lungotevere. The ancient mausoleum of Emperor Hadrian, later turned into a papal fortress, has one of the best views of Rome from its terrace—and a history of intrigue and escapes that’s worth a book. There’s a secret corridor, the Passetto di Borgo, that connected the castle to the Vatican and was used by popes fleeing during invasions.

Where to eat near the Vatican
The Prati neighborhood, immediately north of the Vatican, is where real Romans eat when they’re in this area. Via Cola di Rienzo is packed with bakeries, neighborhood bars, and trattorias without the markup of the immediate tourist zone. A standing espresso at the counter costs €1.20 to €1.50; sitting down and ordering at a table doubles the price—it’s an unwritten rule in every Italian bar.
For lunch, a plate of pasta all’amatriciana or cacio e pepe at a neighborhood trattoria runs €12 to €16. Avoid trattorias with laminated menus and photos in the window—they’re the ones geared toward passing tourists. A sign of a good place is a menu written by hand on a board that changes with the season.
Good gelato around the Vatican exists, but it takes a little searching: covered containers and natural colors are the right signs. The average is €2 to €3 per scoop at an honest place.
Where to stay in Rome
The Prati neighborhood is the most straightforward choice for anyone who wants to wake up near the Vatican: quiet, residential, with a metro (Lepanto or Ottaviano) and a good selection of 3- and 4-star hotels. It’s a 15-minute walk from St. Peter’s Square and has easy access to the rest of the city.
The Centro Storico—the neighborhoods of Navona, Campo de’ Fiori, and the Pantheon—is more expensive and lively, but it puts you in the historic heart of Rome. For those who want the Vatican as a central point and the rest of the city as a complement, Prati makes more sense. For those in Rome for a week who want to explore everything, the Centro Storico is generally more convenient.
The Trastevere neighborhood, south of the Vatican on the other side of the Tiber, offers the most characteristic atmosphere of ancient Rome, with narrow streets and local nightlife. It’s a 20-minute walk from the Vatican—a pleasant stroll along the Tiber’s edge.
Practical tips
Mandatory dress code: shoulders and knees must be covered to enter the basilica. This applies to both men and women. Lockers with disposable shawls are available at the entrance, but it’s more practical to come prepared. Anyone arriving in shorts or a tank top will be turned away at the door—no exceptions.
Audioguides and Masses: the basilica holds daily Masses and is an active liturgical space. During celebrations, part of the nave is closed to visitors. Check the Mass schedule on the Vatican website before planning your visit time. Audioguides are available in English at the entrance for a modest fee.
Why no pope has taken the name Peter: since the first pope—St. Peter himself—no other pontiff has chosen this name. Oral tradition and a prophecy attributed to the medieval monk St. Malachy say that the last pope in history will be called “Petrus Romanus” (Peter the Roman). Adopting the name would be too heavy a symbolic statement—like announcing the end of the Church. It’s not canon law, but the tradition has held unbroken for 2,000 years.
About the three coffins: centuries-old tradition dictated that popes be buried in three nested coffins—one of cypress (symbolizing humility), one of lead (protection), and one of oak or elm (durability). Pope Francis, during his lifetime, approved a reform of papal funeral rites, making burials simpler: he was buried in a single wooden coffin, without the traditional three coffins, reflecting his personal choice for austerity.
Visa: U.S. citizens can enter Italy (and the Vatican) without a visa for stays of up to 90 days. Check the rules for the ETIAS system, expected to come into effect, on the official European Union website before you travel.
Frequently asked questions
Are the Sistine Chapel and St. Peter’s Basilica the same thing?
No. They are two distinct buildings within the Vatican, with separate entrances. St. Peter’s Basilica is the large church with Michelangelo’s dome, accessible for free from St. Peter’s Square. The Sistine Chapel is inside the Vatican Museums complex, with a paid entrance and access through a different door (Via dei Musei). At the end of the museum route, you reach the Sistine Chapel—but they are completely separate locations.
Which pope built St. Peter’s Basilica?
The construction of the current basilica was ordered by Pope Julius II in 1506 and lasted 120 years, passing through several popes. The main architects were Donato Bramante (original design), Raphael Sanzio, Michelangelo (who designed the dome), Giacomo della Porta, and Carlo Maderno (façade). The final consecration took place in 1626, under Pope Urban VIII. No single pope built it—it was a collective work spanning more than a century.
Why can’t you take photos in the Sistine Chapel?
In the 1980s, the Vatican made a deal with the Japanese broadcaster Nippon Television, which paid $4.2 million to fund the restoration of Michelangelo’s frescoes. In exchange, Nippon TV received exclusive rights to images of the restored frescoes. The ban on photography protects this commercial contract. Cameras and cell phones are prohibited inside the Sistine Chapel; guards patrol continuously.
Why was Pope Francis buried outside the Vatican?
Pope Francis, who died in April 2025, was buried in the Basilica of Santa Maria Maggiore in Rome—the first time in more than 120 years that a pope was not interred in the Vatican. The choice was personal: Francis had a deep devotion to the Salus Populi Romani icon housed in that basilica and visited the site regularly. During his lifetime, he himself approved the plans for his burial there.
Why has no pope taken the name Peter?
Tradition and symbolic weight. Since St. Peter, the first pope, no successor has chosen the same name. The medieval prophecy of St. Malachy predicts that the last pope in history will be called “Petrus Romanus.” Taking the name Peter would associate a papacy with the end of times—a burden no pope has wanted to carry. There is no canon law forbidding it, but the tradition has held unbroken for two millennia.
Conclusion
St. Peter’s Basilica condenses 2,000 years of history, art, and faith into a single space. Entry is free, but what you carry in your head when you leave is priceless: the overwhelming scale of the nave, the perfect coolness of the Pietà’s marble, the vertigo of looking down from the top of the dome. Arrive early, cover your shoulders and knees, and set aside at least a full day for the Vatican complex. Rome has much more beyond it—and Voyage Voyage has guides for every piece of that puzzle.
