Saint Sebastian's catacombs, situated in Via Appia, are very important because historians believe that this place had hosted Saints Peter and Paul bodies. They are located in a slope that has always been used as a cemetery also before the Christianism, later it was converted in a cemetery for slaves and freedmen.

The catacombs of St. Callixtus are among the greatest and most important of Rome. They originated about the middle of the second century and are part of a cemeterial complex which occupies an area of 90 acres, with a network of galleries about 12 miles long, in four levels, more than twenty meters deep. In it were buried tens of martyrs, 16 popes and very many Christians. You will also admire the Crypt of St. Cecilia: the popular patron saint of music, she was martyred and entombed where the statue now lies.

Les catacombes de Rome (en italien : Catacombe di Roma) sont d'anciennes catacombes, des lieux funéraires souterrains situés sous Rome, en Italie. On en compte au moins quarante, dont certaines n'ont été découvertes qu'au cours des dernières décennies. Bien que principalement célèbres pour leurs sépultures chrétiennes, soit dans des catacombes séparées, soit dans des catacombes mixtes, des personnes de toutes les religions romaines y sont enterrées à partir du IIe siècle après J.-C., principalement en réponse à la surpopulation et au manque de terrains.
