Catacombs of Saint Sebastian
Local name: Catacombe di San Sebastiano
The Catacombs of Saint Sebastian is an underground cemetery complex in Rome. They are the only Roman catacombs to which access remained open for centuries. They had four underground floors, the first of which was almost completely destroyed. The entrance to the catacombs is open to visitors, located in the Franciscan monastery.
The Roman catacombs contain relics of three martyrs: Sebastian, Kwirin and Eutychius.
In the catacombs of the second century there are three mausoleums, which were discovered only in 1922. They belonged to well-placed people. The first mausoleum belonged to Marek Klodiusz Hermes, the second probably to some association called innocentiores. The third mausoleum, referred to in archaeological sources as the Ax Mausolemum, also belonged to some association.
In the museum inside the Constantine Basilica, fragments of Paleo-Christian sarcophagi from the turn of the 3rd and 4th century are presented.
