The catacombs around Rome are places that always fascinated visitors. Going back to the first century, Christian Romans did not have their place to burry their dead. Until Christianity's acceptance, the Ancient Romans forbade, nor offered a piece of land for Christians to bury bodies in Rome. So before the catacombs, Christian and Jewish had to resort to other pagan common cemeteries. Saint Peter was buried on one on Vatican Hill in the great public "city of the dead" (know as "Necropolis") and Saint Paul was buried in one along the Via Ostience.

In the second century, Christian were granted small pieces land outside of Rome's precincts and started creating subterranean burial places. It became more practical and less costly for Christians to develop underground cemetery complexes than buying open-air properties.

There were about sixty catacombs near Rome mostly along the Appian Way. The ancient Roman catacombs usually started with family tombs but the newly converted Christians did not reserve places and were open for other "brothers and sisters" in faith to be buried around the same tombs.

By the purchase of new land and by gifts, the catacombs eventually expanded to be impressive subterranean complexes of the dead. Sometimes a catacomb cemetery was directly managed by the new emerging Church itself for community purposes. The Saint Callistus (Callixtus) catacomb was a good example were they also put into ground the first Roman bishops and created a Crypt of the Popes.

The persecution of the early Christians were not always equally cruel and universal. There were some higher times of persecution followed by calmer peaceful periods. During the difficult times, the catacombs were sometime used as a temporary place to celebrate the Christian Mass and the Eucharist. However, they were not used as secret hiding places like seen in movies and novels.

In 313 A.D. finally came the edict of Milan ratified by the emperors Constantine and Licinius which gave freedom to the Church. So the Christians became free to have places of worship, build churches inside and outside of Rome and profess their faith. They could also buy properties without the fear to have these confiscated. The catacombs then became pilgrimage centers and shrines of the martyrs into all parts of the Empire.

The catacombs were still used as normal cemeteries until the 5th century. Then the Church started to create basilicas for saints and martyrs and buried the dead mostly above the ground.

Around the 8th to 9th century, because of repeated pillage by the Goths and Lombards barbarians, the Popes ordered to take out the relics from the catacombs to place them in more secure places inside the city's churches. The catacombs then were mostly abandoned to the exception of the Saint Pancratius and Saint Lawrence ones. Over time, vegetation and landslides blocked the entrance to many catacombs and were mostly forgotten throughout the Middle Ages.

It is only later, in the beginning of the 17th century, that scientific studies of the catacombs, led by Antonio Bosio started. He was named the "Columbus (discoverer) of the underground / subterranean Rome. Then in the 19th century was made more systematic exploration of the catacombs by Giovanni de Rossi who brought to light the wonders of the Saint Callistus (Callixtus) catacomb in particular. Giovanni de Rossi is known to be the founder and father of Christian Archaeology.
