Catacomb from the late third to the fifth century, which continued to be visited until the high Middle Ages as a shrine of the martyr with the same name.

The “historical crypt”, the center of devotion to the martyr Senatore, has a remarkable monumental impact like the remaining part of the cemetery entirely dug out in the areas of an ancient sandstone quarry which had already housed a pagan funeral hypogeum in the first half of the third century.
