Basilican Church of St Peter Rome

The basilican church of St Peter Rome is the Renaissance basilica at the western end of St. Peter’s Square, and it is the most important church in Catholic Christianity. Visitors can enter the main church, climb the dome with a timed ticket, or go underground to the Necropolis. In this guide I explain what each part of the visit involves, what the rules are and how to book the extras without wasting a morning in line.

I’ll keep to what the official sources say. Where you see a link, it points to the Vatican’s own pages, Wikipedia or Wikidata, so you can check the detail yourself. For the complete overview, my full St. Peter’s Basilica guide covers every part of the visit.

Is it a church or a basilica?

A church or a basilica is a false choice here, because the building is both. “Basilica” is its rank and architectural type, while “church” describes how it is used, so the basilican church of St Peter Rome and St. Peter’s Basilica are the same place. To get the wording sorted out, I wrote about the church-and-basilica distinction in a separate page.

The church sits in Vatican City, not in the Italian city around it. Wikipedia describes the neighboring square as a large plaza directly in front of St. Peter’s Basilica in Vatican City, the papal enclave in Rome. That is why people say “Rome” in everyday speech and “Vatican” on maps. If you are wondering is St. Peter’s a church inside Vatican City?, the answer is yes.

Basilican church of St Peter Rome by the numbers

The basilican church of St Peter Rome by the numbers comes down to a handful of figures that help you picture the site before arrival. Each one is drawn from Wikidata or the basilica’s own dome page.

• Vatican City area: 0.44 km². The whole state is smaller than most city parks, so everything is walkable.
• Founded as a state: 11 February 1929. Before that, the papal enclave had no separate legal status.
• Population: 949 in 2024. Most people you see inside are visitors.
• Heritage status: World Heritage Site. Expect strict rules on behavior and dress.
• Square architect: Gian Lorenzo Bernini, in the Italian Baroque style. The colonnades are the first thing you walk through.
• Dome height: the inner dome of the lantern reaches 117 metres, and the cross is over 133 metres. That is why the climb feels serious.
• Dome mosaic: about 3,000 square metres of gold-ground mosaic. Look up from inside the church.

How the church came to be

The church came to be because of a cemetery. According to Wikipedia, the Vatican Necropolis, a group of mausoleums dated between about AD 130 and AD 500, was partly torn down and filled with earth to support the first basilica under Constantine around AD 330. The grave of the apostle was the reason for building there.

The church you see today replaced that older building. Bernini’s square came much later: the open space was redesigned from 1667 to 1676 under Pope Alexander VII, so that the greatest number of people could see the pope give his blessing. The Egyptian obelisk at the center had been raised on the site in 1586.

The dome, step by step

The dome was conceived by Michelangelo, who built it up to the drum. After he died, Giacomo della Porta finished it with Domenico Fontana, working from 1588 to 1590 and raising it in just 22 months with 800 labourers. On 18 November 1593 the gilded bronze sphere and cross were placed on the lantern.

The mosaic decoration came after that, between 1598 and 1613, under Marcello Provenzale. A band of blue letters on gold at the base quotes the words to Peter: “You are Peter and on this rock I will build my church.” When you stand under it, you are reading the reason the church exists.

Start in St. Peter’s Square

St. Peter’s Square is where most visits begin, and it is part of the experience. In its center stands the Vatican obelisk, an ancient Egyptian obelisk erected on the current site in 1586. Bernini designed the colonnades almost 100 years later, using the Tuscan order in four columns deep, so that they would not compete with Carlo Maderno’s palace-like facade.

Two fountains frame the obelisk. Wikipedia dates the granite fountain by Bernini to 1675 and the matching one by Maderno to 1613. I like to pause between them and look back at the facade before joining the line, because once you are inside the security area you rarely get the full view again.

The colonnades were designed so that large numbers of people could see the pope give his blessing. Online buyers follow the assigned route, Sobieski or Lambertini, given with their QR codes, so check which one you were assigned before you walk toward the entrance.

If you booked a tour, remember that guides often meet you away from the square. One listing sends you to Via di Porta Angelica, another to a cafe in the Leonine City, and a third to an office near the Ottaviano metro stop. Read the meeting point twice, because arriving at the colonnade by habit is the classic mistake.

How do you get in and what does it cost?

Getting in to the main church is where most visitors start, and it needs no ticket. One reviewer said it plainly, and I’d agree with the practical point about timing:

“Do not miss this place for a FREE location! This is the most beautiful church I've ever been to. Once your through security and the main doors, you are truly hit by the size and artwork. We got there 645am and already there's a line but got in very quickly. If your just there for free visit, you can see most of it in 40mins. Pay extra for the other locations.”

Opening hours on the map listing for the basilica run 7 am to 7:10 pm every day. Hours can change for papal ceremonies, so confirm them on the official visitor pages the day before you go.

My advice is simple. Arrive early, expect a security check in the square, and decide beforehand whether you want only the church or also the dome. If you want the church plus a skip-the-line option, you can book Vatican tickets online and see what each ticket includes.

What is the dress code?

The dress code requires covered shoulders and knees. The basilica’s dome FAQ states that clothing appropriate for a place of worship is required, and I’d treat that as the rule for the whole visit, not only the climb.

Pack a light scarf or a long-sleeved layer. Large backpacks, trolleys and bulky luggage are not allowed on the dome route, and the same FAQ says there is no cloakroom or luggage storage. Leave the big bag at your hotel.

Climbing the dome of the basilican church of St Peter Rome

Climbing the dome is the one part of the church that needs a timed ticket. According to the official FAQ, the visit lasts about one hour on average, depending on your pace.

A lift goes only as far as the terrace level. From the inner ring you climb 320 steps to the outer ring. That means the lift option helps with the first part but does not remove the stairs.

The official page describes the dome as “double-shelled with a cavity.” The climb ends on the outer ring, and the lift stops well before it, so decide before you book whether 320 steps suit you.

What the dome ticket includes

The dome ticket you buy online includes entry to the basilica, to be done 90 minutes before your dome time, and the digital audio guide. After booking you receive emails with a voucher and QR codes, and the QR codes are mandatory at the entrance. If the second email does not arrive within 30 minutes, check spam and write to the booking address in the official FAQ.

You also still pass the security check in St. Peter’s Square, and online buyers follow an assigned route, Sobieski or Lambertini, given with the QR codes. The official site also says to expect that security checks stay mandatory for everyone.

Who is buried under the basilica?

Saint Peter is buried below the high altar, according to tradition. Wikipedia’s article on the site says it includes several graves and a structure said by Vatican authorities to memorialize the location of Peter’s grave.

The evidence is careful rather than absolute. Pope Pius XII stated in December 1950 that no bones could be confirmed as Peter’s with absolute certainty, and on 26 June 1968 Pope Paul VI said the relics had been identified in a manner considered convincing. As the encyclopedia puts it:

“Peter's Basilica that includes several graves and a structure said by Vatican authorities to have been built to memorialize the location of Saint Peter's grave.”

The official Necropolis page describes the tour as a way to see a “city of the dead” that stayed inaccessible and untouched for sixteen centuries. You request a reservation through the official booking page, and I’d do it well ahead, since this is a small-group visit. If you would rather see how Rome frames the saint’s church, read how Rome treats St. Peter’s for the city view.

St. Peter’s church in Rome tickets explained

St. Peter’s church in Rome tickets come in several types through GetYourGuide, and the right one depends on what you want to see. The table below compares them using the listing data. Prices are in US dollars as listed and can change.

If your main goal is the church and the dome, I’d start with the first two. The tours below suit travelers who want the basilica with a dome climb or with a guide.

One traveler on the priority access tour wrote that the guide made the visit easy to recommend:

“Valerio was a great guide! We would highly recommend this tour!”

Reviewers on the fast-track dome listing mention that clear information on whether a live guide is included would help, so read the inclusions before paying. For the meeting point on that listing, look for a white tent and staff in yellow vests on Via di Porta Angelica. The other listing meets at Caffè Leonina, and the museum combinations meet at their own offices, so check each booking.

From the Vatican Museums to the basilica

The route from the Vatican Museums to the basilica stays inside Vatican City, but combined museum tours treat the basilica differently. Some list basilica entry as optional, and one says a guided tour of the basilica is excluded. That is the detail that trips up travelers, and reviewers on a museums listing asked for clearer information on what the basilica part includes.

If you want a long day with art first and the church second, the combined options below are the ones to compare. I’d confirm the basilica option is selected before checkout, because skipping that step is the usual reason people end up in a second line. Compare the inclusions line by line before you decide.

Plan the rest of your visit

Planning the rest of your visit is easy, since the church sits beside services you may need. The map data shows a tourist information office in the square, open 8:30 am to 6:30 pm Monday to Saturday and closed on Sunday, plus a souvenir shop and a brunch spot a short walk away.

Final checklist for the basilican church of St Peter Rome

The final checklist is what I would do, in order. First, decide if you want only the main church, which needs no ticket, or also the dome or the Necropolis, which do. Second, book timed entries early on the official site or through a listed tour. Third, dress with shoulders and knees covered, and bring only a small bag.

On the day, carry your QR codes on your phone or on paper, arrive early for the security check and allow about an hour for the dome. Prices, hours and closures change, so confirm them on the official basilica site before you travel. If you also want tickets for the museums, I’d see every ticket type side by side and pick the one that matches your plan.
