2 Tombs to explore in Vatican City
It is the smallest country in the world, and the center of Roman Catholic Church.
Located under St. Peter's Basilica, it was built to memorialize the location of Saint Peter's grave. The complex consists of several graves, and it is was partially torn down during the reign of Constantine I in about AD 330 to provide the foundation for the first St. Peter's Basilica.
The suspected grave of Apostle Peter is located in the Vatican Necropolis. The Necropolis lies nder the Vatican City, 5-12 meters below Saint Peter's Basilica, and it was originally a burial ground outside of the the city walls of Rome. Guided tours can be arranged here in advance, if you contact the office of the Vatican sponsored archaeological excavations(scavi).
