As clearly indicates their name, the catacombs were located at the tenth mile of the ancient Latin Way (today at the height of km. 6 the Via Anagnina). These catacombs are among the most famous in the area for the excellent state of conservation of two galleries excavated in the tufa and with a barrel vaulted ceiling, which branch out in minor arms for a total of 225 meters. The two galleries have a difference in height of about one meter, for this call are the catacombs to double continuous plane. At the entrance is visible the arcosolium with a candlestick of marble used as pillar; inside are kept approximately one thousand tombs (II-V century d.C.), most of which are still intact and some wall paintings of the IV and V century to note are the marble slabs positioned to close the niches, distinct from epigraphs and graffiti, modest, that indicate the character poor of construction.
