Beneath the Heart of Rome: A Peek into Christianity's Mysterious Ancient Tombs

Beneath St. Peter's Square, you'll find a collection of antique tombs, each holding a piece of the puzzle from Christianity’s early years. These include the heart of St. Peter's Basilica, the tombs of the Early Christian Period, and those surrounding the Papal Basilica of St. Peter in the Vatican, the largest church in the world by interior measure. Emperor Constantine the Great commissioned these tombs in 320 AD, and they house the remains of key figures from Christianity’s formative era.

**The tomb of the apostle Peter** - It's often claimed to be the burial place of the apostle himself. Discovered in the 1950s, this tomb rests within a stone sarcophagus, making it the Arch Basilica's most significant site of Christian pilgrimage.

**The tomb of Pope St. Marinus** - The first Roman pope to reside here, St. Marinus is traditionally linked to the popular tale of the sinking of Palma. His remains were found in the 17th century by Pope Paul V who built a church above his tomb.

**The tomb of Aureliano** - This is the fourth tomb beneath the square, that of the martyr Aureliano, baptized by Peter. Although not an apostle, his connection to Peter, his martyrdom, and the state of his uncorrupted body make his tomb intriguing.

**The tomb of St. Pantaleon** - Sculpted from marble in the 16th century, the tomb of St. Pantaleon, the least known of the four, is still a site of significance. Pantaleon’s link to Peter, his martyrdom at the Roman Colosseum, and the fact that his body has remained uncorrupted, keep his tomb a subject of curiosity.
