Planning your first visit to Rome and wondering if climbing St Peter’s dome is worth the effort (especially in the heat of June)?
Maybe you’ve heard mixed reviews about the narrow staircases, worried about dress codes being enforced, or questioned whether the 551-step climb (or 320 with the elevator) is manageable.
Having dealt with the summer heat while wearing a long skirt and experienced the narrow spiral staircases firsthand, I’ll share the insider knowledge that makes the difference between a stressful visit and an unforgettable one.
Whether you’re a budget traveler trying to make the most of your visit to Italy or someone with mobility concerns weighing the elevator option, this guide addresses the realities of the dome climb.
By the end of this guide, you’ll know exactly what to expect, what to wear, and how to make the most of that breathtaking 360-degree view of Rome that makes every step of the climb absolutely worth it.
How Do I Get Tickets to Climb St. Peter’s Dome?
You can either book a ticket to climb the dome via only the stairs or with the elevator (lift).
- Basilica + Dome with stairs – €17
- Basilica + Dome with lift – €22
**Prices last verified February 2026
You must reserve tickets in advance, either way, as there are scheduled entry times.
There is not much to see if you choose to walk the whole way, however, there’s no line for the stairs while the elevator does typically have one.
I will note that, since I had my shoulders and knees covered (in respect), and it was summer when I went, it was rather hot. That’s something you’ll want to consider when making your decision on which way to climb the dome.
A ticket will also include a visit to Saint Peter’s Basilica with a Digital Audio Guide.

What’s the Dress Code?
The Vatican has strict clothing rules, so don’t make the mistake of going in wearing:
- Sleeveless and / or low-cut garments
- Shorts above the knee
- Miniskirts
- Hats
I wore a sleeveless black shirt that I put a red camisole over that I could tie on at the front.
This was a brilliant pick as I could take off the red top after I’d left and just put it in my bag since it was lightweight and balled up easily.
My first mistake, however, was wearing a long skirt instead of light pants.
I found that I had to be careful going up the dome’s stairs to avoid tripping.
I was also a bit heavier at this time and often had chaffing issues. Still do depending on what I wear, but if you also encounter this, check out the Megababe Thigh Rescue Anti-Chafe Stick.
And yes, they do enforce these rules. Shortly after my visit, my cousin went with her immediate family and wasn’t allowed in because her skirt was too short (it ended above the knee).
When is the Best Time to Climb St. Peter’s Dome?
The best time to climb St Peter’s dome is early morning, when there are fewer crowds.
As I visited the Vatican Museums before moving on to the Basilica, I found myself ascending around 2 pm.
Not a wonderful idea in June, when temperatures in Rome are around 77°F to 85°F.
But I only had 3 days in Rome and was making the best of it!
If I were to redo this, I’d go earlier in the day and leave the Museums for the afternoon since they are mainly indoors.
Dome Opening Hours:
- Winter period: (26 October 2025 – 28 March) 7.30am – 5pm
- Summer period: (29 March 2026 – 25 October 2026) 7am – 6pm
Should you be visiting Vatican City in December, note that it is one of the best places to visit for Christmas in Italy.
What is the History of St. Peter’s Basilica?
St. Peter’s Basilica in Vatican City is one of the most iconic religious buildings in the world, with a history stretching back nearly 1,700 years.
St. Peter’s is the most renowned work of Renaissance architecture and the largest church in the world, and has been described as “the greatest of all churches of Christendom.”
Even if you aren’t religious, it’s still truly an architectural marvel.
Origins
According to tradition, it is built over the tomb of St. Peter, the apostle and first pope, who was martyred in Rome around 64–68 AD.
Emperor Constantine I constructed the first basilica on the spot around 320 AD, a large five-aisled church that stood for over a thousand years.
The Old Basilica’s Decline
By the 15th century, the original Constantinian basilica had fallen into serious disrepair.
Pope Nicholas V first proposed rebuilding it around 1450, but not much happened until Pope Julius II came along in 1506 and made the bold call to tear the whole thing down and start from scratch.
Construction of the New Basilica
What followed was one of history’s greatest (and longest) architectural endeavors, spanning over 120 years and cycling through the greatest artists and architects of the Renaissance and Baroque periods.
Donato Bramante drew up the original plans, followed by Raphael, Antonio da Sangallo the Younger, and then Michelangelo, who took over in 1546 at the age of 71 (not exactly a retirement project).
Michelangelo redesigned the building and was largely responsible for the iconic dome, though he didn’t live to see it finished.
Carlo Maderno later extended the nave and added the famous facade.
Gian Lorenzo Bernini completed the interior and designed the magnificent colonnade surrounding St. Peter’s Square, wrapping the whole project up in 1626.
Today it remains the spiritual heart of the Catholic Church and one of the most visited sites on earth.
Highlights at Saint Peter’s Basilica
Art by Michelangelo
The first thing that strikes you as you enter St Peter’s Basilica is not only how immense it is but also how beautiful it is.
Probably the most famous work in there is The Pietà (1498–1499), created by Michelangelo Buonarroti.
This famous work of art depicts the body of Jesus on the lap of his mother, Mary, after the Crucifixion.
The statue was commissioned for the French Cardinal Jean de Bilhères, who was a representative in Rome.
It was made for the cardinal’s funeral monument but was then moved to its current location.
Fun fact: The Pieta is the only piece Michelangelo ever signed.
Bernini’s Baldachin & the Tomb of St. Peter
The Baldachin (or baldacchino) is the enormous bronze canopy standing over the tomb of St. Peter and beneath Michelangelo’s dome.
At roughly 29 meters tall (95 feet), that’s basically the height of a four-story building, making it one of the largest bronze structures ever cast.
It’s one of those things that genuinely stops you in your tracks the moment you walk through the doors because of its sheer scale.
The goal was to create a grand focal point marking the precise spot believed to be St. Peter’s tomb, while visually tying together the papal altar below and that enormous dome above.
And honestly, it works. Your eye travels straight up from the altar to the baldachin to the dome without even trying.
Oh, and the architect, Gian Lorenzo Bernini? He was just 25 years old when he got the commission. Twenty-five. Most of us are figuring out how to do laundry at that age.
🎥 Movie buffs may recognize the high altar from the climax of the Angels and Demons film.
Though the film wasn’t actually shot here, so don’t get too excited if you’re a film tourist.
Statue of St. Peter
Seated in the right nave of St. Peter’s Basilica, the bronze statue of St. Peter is one of the most venerated objects in the Catholic world and will likely catch your eye as you’ll see a line forming near it.
This line is created so people can rub or kiss the bronze statue’s right foot, a centuries-old tradition to show devotion, seek a blessing, and ask for the saint’s help.
The foot has literally been worn smooth by millions.
St. Peter’s Chair
St. Peter’s Chair (Cathedra Petri) is one of Bernini’s most theatrical works.
It’s located at the far end of the apse, directly opposite the entrance, so you’ll see it the moment your eyes adjust to the interior.
At the heart of the monument is an ancient wooden chair, long venerated as the actual throne used by St. Peter himself when he preached in Rome.
Which is an incredible claim, so scientific analysis in the 1960s instead discovered the wooden chair likely dates to the 9th century, possibly a gift from Holy Roman Emperor Charles the Bald to Pope John VIII around 875 AD.
So, probably not Peter’s actual chair. But it remains one of the most symbolically important objects in the Catholic Church.
The chair symbolizes the authority of the papacy—cathedra, the Latin word for the seat from which a bishop teaches, is literally the origin of the word “cathedral.”
Fun fact: So every cathedral in the world is named after a chair.
Pope Tombs & Remains
Scattered around St Peter’s, you’ll find many monuments, tombs, and remains of various Popes throughout the millennia.
Some of the ones that stood out to me are:
🏛️ Tomb of Pope Gregory XIII
If the name Gregory XIII doesn’t immediately ring a bell, here’s your fun fact for the day: he’s the pope responsible for the Gregorian calendar (you know, the one the entire modern world still uses).
Not a bad legacy.
His tomb, created by Camillo Rusconi in the early 18th century, depicts Gregory seated in full regalia above a relief panel showing the calendar reform itself, flanked by allegorical figures.
It’s one of the more narratively interesting tombs in the basilica.
⚰️ Mortal Remains of Pope John XXIII
This one hits a little differently than the other tombs in the basilica—and it’s not because Pope John XXIII is one of the most beloved figures in modern Catholic history.
It’s because his remarkably preserved body lies in a crystal reliquary beneath the altar of St. Jerome’s Chapel.
Kinda reminded me of that scene in Snow White after she’s eaten the apple and the dwarves have put her in the glass coffin.
John XXIII served as pope from 1958 to 1963 and is best known for convening the Second Vatican Council, which modernized the Catholic Church in ways still felt today.
He was canonized as a saint in 2014, which is why he gets the full reliquary treatment rather than a standard tomb.
His preservation is considered by the Church to be remarkable, though it’s worth knowing he was embalmed and has been treated over the years, so there is that.
Art Around the Basilica
This one is worth knowing before you visit, because there’s a small catch that trips up many first-time visitors.
The altarpiece you’re looking at is actually a mosaic copy of Raphael’s Transfiguration, not the original painting.
The original hangs in the Vatican Pinacoteca (the art museum within the Vatican Museums complex).
Raphael’s Transfiguration was considered his greatest masterpiece at the time of his death in 1520, and it was displayed at his funeral before eventually making its way to the Vatican.
The scene depicts the moment Christ appears in radiant glory before Peter, James, and John on Mount Tabor, so there’s a certain poetry to a version of it living here permanently, in a basilica dedicated to Peter himself.
The Dome & Ceiling Work
One mistake you should not make is forgetting to look up while touring the Basilica!
It honestly was my favorite thing to see during my visit.
From the ornate mosaics to the guilded elements, it was almost too much to take in.
As for Michelangelo’s dome, it soars 136 meters (448 feet) from the floor to the top of the lantern, and the scale of it doesn’t fully register until you’re standing underneath it with your neck craned back.
The interior of the dome is covered in elaborate mosaics of rich gold, deep blues, and figures of saints and angels that get progressively more detailed the longer you stare.
Running around the base of the drum in large bold lettering is the Latin inscription: Tu es Petrus et super hanc petram aedificabo ecclesiam meam — “You are Peter, and upon this rock I will build my church.”
The letters are over six feet tall, which you’d never guess from the floor.
Also known as the “cupola,” Michelangelo began construction on the dome in 1547.
By the time of his death (he died at 89 in 1564), construction had reached the drum of the dome. Then, Giacomo Della Porta, Michelangelo’s pupil, took over the project.
He then completed it in 1590, in just 22 months, under the pontificate of Pope Sixtus V.
St Peter’s Basilica dome has since been used as a model for others around the world:
- Saint Paul’s in London (1675)
- Les Invalides in Paris (1680-1691)
- Capitol building in Washington (1794-1817)
Guide to Climbing St Peter’s Dome
Climbing St Peter’s dome was one of the highlights of my trip to the Eternal City.
The view was absolutely incredible!
To get to the dome, follow the signs for “Cupola” in St Peter’s Basilica until you reach the ticket office.
This is also where the elevator that takes you up to the dome is.
From here you have two options for climbing St Peter’s dome:
1. Climb all the way up on foot (551 steps)
2. Take the elevator and then climb the rest on foot (320 steps)
If you take the elevator, you will reach an interior balcony, the first level, which is actually the base of the dome.
If you take the stairs all the way (like me), there’s not much to see, so if you take the elevator, you’re not missing out on much.
I primarily took the stairs just to save a bit of money; however, if I were to go back, I’d still take the stairs unless I was with someone with mobility issues and was trying to reduce the number of steps, as the elevator line can be long.
The Lower Terrace
At this level, you can look down onto the Basilica from above (which was incredible by the way).
You can then move onto the terrace, where you can stop to catch a breather and get access to bathrooms, a water fountain, a souvenir shop, and a café.
I was actually really thirsty and hot by this point, so I went and got a cup of water.
They will charge you for even a small cup of water, so just be prepared for that.
My mistake here wasn’t knowing about the water fountains and instead going to the guy behind the counter who charged me.
Alternatively, I could have brought a plastic (not glass) water bottle with me on this trip.
From this terrace, you can see the Piazza and the massive statues of the apostles!
The Final Ascent
After your short break, you head up the spiral staircase to the lantern.
Be forewarned that if you’re not a fan of small spaces or have trouble with stairs, this may not be for you.
I wound up walking up the steps with some lovely people, and we all had to pause occasionally while climbing St Peter’s dome.
I felt lucky to chat with them as I was solo and it made me feel less terrible that I had to even rest as a 25 year old.
It’s a narrow staircase only broken up by some small windows. I recall this portion of the ascent took about 15-20 minutes. However, this obviously depends on your speed.
This Youtube video gives you an idea of what the ascent is like with it’s leaning walls that echo the shape of the dome as well as the small spiral staircase.
From my experience, I had to be careful with my skirt so I wouldn’t trip, which is what I recall most.
That, and feeling the cool of the walls under my fingertips, which did help me balance and regulate my temperature a bit.
Is the View from the Top Worth It?
Even if you struggle a bit, as I did, especially with my warm outfit and skirt, it is well worth it once you see the 360º view of Saint Peter’s Square and the city of Rome from the very top.
Once you’re up here, you’re welcome to hang out for a bit and are not rushed off, so if you need to take a break while taking in the view, that’s totally okay!
Do note that there are no facilities up here like there is on the lower terrace however.
On the way down, there is a separate walkway so you won’t be a salmon swimming upstream, which I find to be a delight as I’ve gone up one too many cramped staircases where this wasn’t the case.
The estimate for this experience is an hour, depending on your speed and how much time you spend up there.
As for those with mobility concerns, be aware that even the elevator option still involves 320 steep steps through a narrow spiral.
You could just go to the lower terrace, but the real magic is at the lantern, so if you’re still set on going, I’d recommend going early for fewer crowds, as that’ll lessen the pressure and also be cooler. Alternatively, toward the end of the day would also be good for these reasons.
FAQs
Can you go up the dome in St. Peter’s Basilica?
Yes, visitors can climb the dome of St. Peter’s Basilica in Vatican City.
There are two options: climb all 551 steps on foot (€17, prices verified February 2026), or take the elevator partway and climb the remaining 320 steps (€22).
Both require advance reservations with a scheduled entry time.
The climb passes through a lower terrace, where there are bathrooms, a café, and views down into the Basilica, before a final narrow spiral staircase leads to the lantern at the top.
The full experience takes approximately one hour, depending on pace and crowds.
Visitors must comply with the Vatican’s dress code: no sleeveless tops, no shorts above the knee, no miniskirts, and no hats (enforced at the entrance).
How long does it take to climb St Peter’s Dome?
Climbing St. Peter’s Dome takes approximately one hour from start to finish, though this varies by pace and crowd levels.
The climb breaks into two stages: first, reaching the lower terrace (via 551 stairs or the elevator plus 320 stairs), where there are bathrooms, a café, and views down into the Basilica below.
From the lower terrace, the final spiral staircase to the lantern takes approximately 15 to 20 minutes. It’s narrow, slightly leaning (following the dome’s curve), and only broken up by small windows.
Once at the top, there’s no time limit, so you can linger and take in the 360-degree view for as long as you like.
Budget extra time during peak summer months, when crowds significantly slow the ascent, especially on the spiral staircase.
I climbed on a June afternoon and found it hot inside the stairwell, which required me to take breaks.
Can you climb St Peter’s Basilica for free?
No, climbing the dome of St. Peter’s Basilica is not free.
Tickets cost €17 for stairs only, or €22 for the elevator plus stairs (prices verified February 2026).
Advance reservation with a timed entry slot is required, as walk-up tickets may not be available during peak season.
However, entry to St. Peter’s Basilica itself, the interior of the church, including Michelangelo’s Pietà, Bernini’s 95-foot bronze baldachin, and the papal tombs, is free.
The Vatican Museums and Sistine Chapel are a separate paid attraction (approximately €20 for skip-the-line access).
St. Peter’s Square and the exterior colonnade are free to visit at any time.
If budget is a concern, you can skip the dome and still spend a full morning in the free basilica interior, which contains centuries of art and architecture well worth the time on its own.
Is St Peter’s Basilica Dome worth it?
Yes, climbing St. Peter’s Dome is worth it.
The 360-degree view from the lantern, 136 meters (448 feet) above the ground, is one of the best panoramas in Rome.
From the top, you can see St. Peter’s Square, the Tiber River, and on a clear day, much of the Roman skyline.
The experience also lets you see Michelangelo’s dome architecture from the inside—the mosaics, the Latin inscription at the base of the drum in letters over six feet tall, and the perspective down to Bernini’s baldachin far below.
The caveats: the final spiral staircase is narrow and steep, and in summer the heat inside can be intense.
I climbed in June in the afternoon in a long skirt and found it difficult. Early morning would be more breathable.
For most visitors in good health, the view justifies every step.
