Where is St. Peter’s Basilica in Vatican City?

One of the most common misconceptions about visiting the Vatican is assuming everything is in the same place. It’s not.

St. Peter’s Basilica sits on the southeastern side of Vatican City, directly overlooking St. Peter’s Square. It’s the enormous church with Michelangelo’s famous dome that dominates the Vatican skyline, and it’s usually the first thing you’ll see when approaching from Rome.

Importantly, the basilica entrance is not the same as the entrance to the Vatican Museums.

• St. Peter’s Basilica entrance: through St. Peter’s Square (security line in the square)
• Vatican Museums entrance: on Viale Vaticano, about a 15–20 minute walk away

It’s an easy mistake to make, and one that can cost you time, so double-check which entrance you need before you go.

Must-See Highlights Inside St. Peter’s Basilica

With so much to see inside St. Peter’s Basilica, it can be hard to know where to focus first. Beyond its sheer size and grandeur, the basilica is packed with artistic masterpieces, hidden symbolism, and centuries of history. Here are the highlights you absolutely shouldn’t miss.

Michelangelo’s Pietà

Just inside the entrance, to the right, you’ll find one of the most famous sculptures in the world: Pietà. Michelangelo carved it when he was just 24 years old, and it remains one of the greatest masterpieces of the Renaissance. Look closely at the serene expression on Mary’s face, remarkably, Michelangelo chose to depict her as youthful and calm, emphasizing purity and grace rather than grief.

Bernini’s Baldacchino

Standing directly beneath the dome is Bernini’s enormous Baldacchino, the bronze canopy over the papal altar. At 96 feet (29 metres) tall, it’s nearly the height of a 10-storey building and marks the symbolic heart of the basilica, directly above what many believe to be the tomb of St. Peter.

The Papal Altar

This is the main altar of the basilica and one of the holiest places in Catholicism. Unlike most church altars, it can only be used by the Pope. It sits directly above the underground shrine linked to St. Peter himself.

Michelangelo’s Dome

Even from the basilica floor, the dome is one of the most awe-inspiring sights in Rome. Designed by Michelangelo, it rises 452 feet (138 metres) and floods the basilica with natural light. If you have the energy, climbing to the top rewards you with one of the best views in the city, just beware there are over 500 stairs to climb.

The Vatican Grottoes

Beneath the main floor lies a quieter, often-overlooked part of the basilica: the Vatican Grottoes. Here you’ll find a vast underground crypt area containing the tombs of dozens of popes, including Pope John Paul II, along with chapels and remnants of the original 4th-century church. Many visitors miss this section entirely—but it’s one of the most atmospheric parts of the basilica.

These are generally free to visit once inside the basilica and do not require advance booking. Access is usually through a staircase near the papal altar area/the transept of St. Peter’s Basilica.

The View of  St. Peter’s Square

Before you leave, take a moment to turn back toward the entrance and look out over St. Peter’s Square. From inside the basilica, you get a stunning framed view of Bernini’s famous colonnades, one of the most iconic scenes in all of Rome.

Practical Tips for Visiting St Peter´s Basilica

With so much to see inside St. Peter’s Basilica, it can be hard to know where to focus first. The good news? Much of what makes the basilica extraordinary is included in free general admission. But some of its most fascinating areas, like the dome and the ancient tombs below, require an extra ticket or advance booking.

Here’s how to make the most of your visit:

Opening Times

The Basilica is open every day, and visitors can enter the Basilica for free.

• From 7:00 a.m. to 7:00 p.m. April to September
• From 7:00 a.m. to 6:00 p.m. October to March.

Hours can vary on religious holidays, so check the official website before your visit.

What can you see for free inside St. Peter’s Basilica?

Once you’ve passed through security (which can take anywhere from 20 minutes to 2 hours depending on the season), entry to the basilica itself is completely free.

That includes access to the main nave, chapels, side aisles, and many of the basilica’s greatest masterpieces: including Michelangelo’s Pietà, Bernini’s Baldacchino, the Papal Altar, Vatican Grottoes, and the interior mosaics and chapels.

Insider Tip: Don’t miss the side chapels, papal monuments, and the huge bronze statue of St. Peter near the centre aisle, visitors often touch or kiss his foot for luck, which is why it has been worn smooth over centuries.

Which areas require a ticket?

The Dome (Cupola)

The dome is usually credited to Michelangelo, and rightly so, but the story is more complicated. Several architects worked on the basilica before him, yet Michelangelo dramatically simplified the design and re-focused it around light, symmetry, and scale. His dome was inspired by Florence Cathedral, and remains one of the defining features of Rome’s skyline today.

The entrance is at the portico of the Basilica.  Once up top, you can admire the unique view of the nave and altar, as well as the incredible view over Piazza San Pietro.

The opening hours are usually an hour after general opening to an hour before general closing (so April–September: 8:00 AM–6:00 PM and October–March: 8:00 AM–5:00 PM)

To visit, you’ll need a separate ticket: you can choose from stairs only (10€): cheaper, but involves around 551 steps, or elevator + stairs (15€): slightly more expensive, but still requires climbing the final 320 steps. 

Be warned: the stairs are much more strenuous than the elevator and there aren’t many views to enjoy during your climb.

Insider tip: book this early in the day, queues for the dome can get surprisingly long.

The Vatican Necropolis (Scavi) 

Known as the Scavi, Vatican Necropolis, Tomb of the Dead, or St. Peter’s Tomb, the site is a burial ground dating back to the fourth century. These ancient Roman burial grounds sit even deeper beneath the church and are believed by many to contain the original tomb of St. Peter.

This is the most exclusive part of St. Peter’s Basilica, and the hardest ticket to get. If you can get a spot, it’s one of the most fascinating experiences in Vatican City.

Important to note: Advance booking required

To protect the ancient site, only 250 people are allowed in daily, in small groups of 12.

Admission is 13€ per person and you must book directly through the Vatican Excavations Office, well in advance. In fact, the application process can be complicated so we recommend that you need to make your request at least 2 months in advance. For personal tours, you have to contact the Excavations Office by email and give the names of the participants in your group, language desired, and proposed dates. Eventually, the Office will contact you to let you know if you made it onto the list, and give you the time and date of your tour,

General advice for Visiting St Peter´s Basilica

Arrive early

Dress Respectfully
