Perhaps, one of Rome’s most well-known attractions are the underground Catacombs which run underneath the city. These winding underground passageways and corridors were former burial grounds for residents of Rome from the 2nd century until the 5th century. Their history dates back to Christian persecution in Rome and a need for a space to bury Christian residents that would solve the issue of expensive or seized land in the city, resulting in these underground labyrinths in which many former residents were laid to rest. The pilgrims’ route reaches only a small part of the second floor, which houses the crypts of the Popes of St Cecilia and the Cubicles of the Sacraments.
You can visit the Catacombs on the final day, on route to the airport for the return journey home.
