8 Fascinating Facts About Saint Peter’s Basilica
1. In origins, it was a Circus
The soil where now stands Saint Peter’s Basilica was originally used as the place for the Circus wanted by Caligula, Roman emperor from 37 to 41 AD, close to which they then built a huge cemetery that you can visit still now. More to this great ancient Roman site later in the post.
Caligula’s Circus was expanded by Nero, and this is where Saint Peter Apostle was martyred by being crucified upside down.
2. This is not the original St. Peter’s Basilica
The basilica as we see it today lies on top of the former basilica devoted to Saint Peter Apostle commissioned by Emperor Constantine. The original basilica was smaller than the modern one but had the same orientation.
The switch from the Constantinian building to today’s Basilica was gradual and went through different renovation works. Started by Pope Niccolò V, they lasted for about 150 years and saw a glorious sequence of some of the most famous artists of the time, from Raphael to Michelangelo. The latter, among the other things, designed the dome and personally followed the construction until he died in 1564.
3. Charlemagne was crowned here
The interior of the majestic basilica enshrines a fascinating sequence of historical and artistic layers. Some of its historical landmarks are Saint Peter’s Baldachin, a large bronze canopy Baroque-style built in the 17th century by Bernini, and the porphyry ring placed at the entrance Charlemagne kneeled on at his coronation on December 25th 800.
4. The interior is a never-ending sequence of artwork
Saint Peter’s Square and facade are stunning and bear plenty of art and symbols. But wait to go inside to really be amazed by the amount of artwork you will be staring at. Countless statues, fine carvings, and wonderful mosaics make St. Peter’s Basilica one of the world’s most beautiful churches.
5. Michelangelo’s La Pietà bears a sad history
By all means, do not miss the beautiful sculpture La Pietà by Michelangelo, the artist’s first masterpiece, and the only one he signed. With an accurate glance, you will notice that Mary looks younger than her dead son. The official explanation is that Michelangelo was inspired by the verses of Italian poet Dante Alighieri’s commanding Divine Comedy (“O virgin mother; daughter of thy Son“), where Mary is the symbol of purity.
There is another theory, however, that places the sculpture closer to the personal life of the artist. Michelangelo lost his mother when he was only five, and sculpted La Pietà at 24 years of age. In his mind, his mother was a young woman, so it’s not unlikely that he portrayed his mother’s face as he remembered her.
6. Only 3 women are buried inside St. Peter’s Basilica
Popes’ tombs can be found inside the basilica and beneath it, in the crypt (free admission), next to what remains of the walls of the original Constantinian basilica. There are also three women whose resting place is inside Saint Peter’s Basilica, Christina Queen of Sweden patron of arts and music, Matilda of Canossa (or of Tuscany), member of the powerful Italian clan of House of Canossa, and the pious Polish princess Maria Clementina Sobieska.

7. Below the Basilica is an ancient Roman cemetery
Located underneath the main basilica, some 11 meters beneath today’s street level, is an ancient Roman cemetery. It lies right next to the circus Caligula built on the Villa Agrippina that he inherited from his mother and that was later expanded by Nero.
Once open-air, this Roman necropolis under St. Peter’s Basilica hosts the tomb of Peter, found when Pope Pius XI ordered to start digging. In this huge underground cemetery, the graves are mixed, Pagans and Christians, Roman families with their Christian servants buried in the same mausoleum. When the funerary mausoleum are the ones belonging to wealthy families, they even had their own terrace because it was believed that the dead, both owners and servants, would feast together.

8. Michelangelo never saw St. Peter’s dome complete
Designed by Michelangelo, after his death in 1564, his pupil Giacomo della Porta took over the project of St. Peter’s dome. It was completed 24 years after Michelangelo’s death.
The dome has an inner diameter of more than 42 meters and is 136.57 meters tall, making it one of the world’s tallest domes.
