Excavations under St Peters

Around the year 67 A.D. Saint Peter suffered death by crucifixion during the reign of Emperor Nero and was laid to rest in a nearby cemetery on the Vatican Hill. For centuries Christians venerated the tomb of St Peter which was marked with a small monument in the mid 2nd century. In the year 320 the emperor, Constantine, began the construction of a large basilica in honour of St Peter, central to which was a shrine that encased both his tomb and the monument which had been subsequently built above it. In the 16th century Constantine’s basilica, which was in very poor condition, was slowly and carefully deconstructed as a new basilica was built. This new basilica is the current basilica and it was finished in 1626.

In the early 20th century a construction crew stumbled upon parts of an ancient city street of family tombs [a necropolis] which had been filled in by Constantine’s workmen as the first basilica was built on the Vatican Hill.  This necropolis was constructed in the 2nd and 3rd centuries and it began at the Tiber River and stretched to and past Peter’s tomb. Between 1939 and 1950 archaeologists uncovered much of this necropolis, eventually discovering the tomb of St. Peter.

Today it i possible to walk underneath the foundation of St. Peter’s Basilica along the streets of this ancient necropolis. By way of a guided tour, pilgrims learn about the history of ancient Rome, St Peter, and the Church. A visit to the excavations underneath St Peter’s is one of the most important and memorable experiences available.
