The largest religious building in the world, and the most famous church on the planet, St. Peter’s Basilica is the center piece of Vatican City, an enclave within Rome and the smallest country in the world, whose sovereign is none other than the Pope. With all these record-breaking attributes, it’s hard to pass on a visit to Vatican City (a UNESCO World Heritage site since 1984) and its immensely impressive basilica.

What is St. Peter’s Basilica?

St. Peter’s Basilica is the world’s largest religious building, one the holiest Catholic structures in the world, and the center of the independent city-state that is Vatican City.
A basilica is simply a church that has been granted special privileges by the Pope due to its historical, cultural, and/or architectural significance. St. Peter’s Basilica was built over the tomb of St. Peter the Apostle, hence its name.
Where is St. Peter’s Basilica?
St. Peter’s Basilica is located in Vatican City, the smallest country in the world (0.17 square mile), and a city-state enclave that is surrounded by Rome, the capital of Italy.
You can walk the 2.1 miles from Rome’s Colosseum to Vatican City in just 40 minutes. It takes 30 minutes (1.5 miles) to walk from the Trevi Fountain to the basilica.
When was St. Peter’s Basilica built, by whom, and why?
The original basilica (known as Old St. Peter’s Basilica) was built by Roman emperor Constantine in the fourth century. It was gradually replaced by the structure we know today, AKA New St. Peter’s, starting in the 1500s. The new basilica was commissioned by Pope Julius III in 1506 and took around 120 years to be completed.
St. Peter’s Basilica (New St. Peter’s Basilica) was designed and decorated by the most prominent architects and artists of the time: Bramante, Raphael, Michelangelo, Bernini, Maderno, and Della Porta.
The basilica was built over the remains of the first church, as well as over a necropolis where St. Peter the Apostle was buried.

St. Peter’s Basilica’s floor plan takes the shape of a Latin cross, with a long nave leading to the altar, a transept that intersects the nave, and a dome over the crossing. The nave is flanked by aisles on either side, which are themselves flanked by chapels. The length of the main nave is about 722 feet, while the height of the dome from the floor is around 436 feet.

What’s special about the dome in St. Peter’s Basilica?

The dome of the basilica (said to be the biggest in the world) was designed by Michelangelo and completed in 1590 by his student, Giacomo Della Porta. (Michelangelo supervised the project until his death in 1564.)
The dome is massive: It has a diameter of 139 feet and a height of 448 feet (at the top of the cross).
You can climb to the top of the dome by taking the stairs (551 steps) or the elevator. You need to purchase a ticket to access the dome and taking the elevator will cost you a little extra. There’s a little coffee shop at the top so you can sip on an espresso while looking at the view.

Michelangelo’s genius is everywhere in St. Peter’s Basilica:
- In 1596, Michelangelo was appointed chief architect of the basilica and designed and supervised the construction of its vast dome.
- Michelangelo’s Pietà, one of his most famous sculptures, is displayed in the basilica.
While not part of the basilica, the ceiling of the Sistine Chapel and the fresco of The Last Judgement (also in the Sistine Chapel) were both painted by Michelangelo.
Is the Sistine Chapel in St. Peter’s Basilica?
The Sistine Chapel is not in St. Peter’s Basilica, it is on the right of the Basilica and has a separate entrance. You need to purchase a ticket to visit the Sistine Chapel.
