A 400-Year Masterpiece:
Why This Anniversary Matters
The story of St. Peter’s is an epic that spans over a century, involving visionary geniuses like Donato Bramante, Michelangelo Buonarroti, and Gian Lorenzo Bernini. When Pope Urban VIII consecrated the finished Basilica on November 18, 1626, it crowned decades of creative brilliance that reshaped the skyline of Rome forever.
Walking across St. Peter’s Square, embraced by Bernini’s monumental colonnades, it feels like entering another world. The anniversary isn’t just a date in a history book: it’s an invitation to appreciate the sheer scale of craftsmanship that went into creating the largest church in the world. From the gleaming travertine facades to the sheer emotional gravity of the space, St. Peter’s remains the beating heart of Roman art and architecture.
Beyond the Nave: Highlights and The Epic Dome Climb
Once you pass through the heavy bronze doors, the sensory richness of the interior can take your breath away. Here are the unmissable treasures you shouldn’t skip:
Michelangelo’s Pietà: Located just to the right of the entrance, this breathtaking sculpture of Mary holding the crucified Christ was carved by Michelangelo when he was just in his early twenties. Its delicate realism and emotional depth are genuinely hypnotic.
Bernini’s Baldachin: Soaring directly beneath Michelangelo’s dome, this monumental bronze canopy marks the high altar and the tomb of St. Peter. Bernini’s swirling columns frame the altar with theatrical, baroque grandeur.
The Grottoes: Beneath the floor of the main basilica lie the papal grottoes, where numerous popes and historical figures rest in quiet, solemn corridors.
The Ultimate View:
Climbing St. Peter’s Dome
If you want a memory that will stay with you forever, lace up your comfortable walking shoes and head for the dome. Designed by Michelangelo and completed by Giacomo della Porta, the dome offers two options:
- take the elevator to the roof level and climb the remaining 320 steps
- or tackle all 551 steps on foot from the ground.
We know it’s a workout and the spiral staircases get narrow near the top. But once you step out onto the outer gallery and look down over the geometric perfection of St. Peter’s Square—with the sprawling rooftops of Rome fading into the horizon—every drop of sweat is instantly worth it.

Tickets, Lines & Insider Tips
Let’s talk about the elephant in the room: tickets and lines. Visiting St. Peter’s Basilica is free, but there are a few things you should know before you go. Here’s how admission works and how to plan your visit without unnecessary surprises.
General Entry to the Basilica: Free or €7 with a Reservation
You can enter St. Peter’s Basilica for free without booking a ticket, but you’ll have to join the general admission queue. Depending on the time of year, waiting times can be very long, especially during peak season and major religious celebrations.
Alternatively, you can book a €7 time-slot reservation online. This allows you to plan your entry more easily, but it doesn’t let you skip security checks: all visitors must go through the mandatory security screening, so some waiting time is still to be expected.
Dome Access: Buying Your Ticket on the Day
If you decide to visit the Dome once you’re inside the Basilica, you can purchase a ticket at the ticket office on the day of your visit, after going through the Basilica entrance queue and security checks. This option is subject to availability.
On-site prices are:
- €10 to climb all the way up by stairs.
- €15 to take the elevator partway up.
Tickets can be purchased at the designated ticket offices: Portico Desk (for access by elevator) and Treasury Museum ticket office (for access by stairs).
