St. Agnes Catacomb:
Existing from the 3rd century and used up to the fifth, it consists of three levels.
It is not very large but has all the characteristic of all other Christian burials, except the frescoes. On the other site is very well connected by B line subway, sant’Agnese/Annibaliano stop. This catacomb is worth the visit due to the proximity of the splendid Mausoleum of Santa Costanza with its 4th century mosaics. The remains of the 4th century constantinian basilica and the actual one.
