Christian communities became important in Tunisia between the fifth and seventh centuries, reoccupying and adapting Roman cities and building large walled enclosures. This is reflected in the twenty-one photographs from that period, displayed in 1892 as part of the fifth frame devoted to "Basilicas, tombs and various monuments of ancient times".
The images show the walls and fortresses of Sbiba, Beja, Tebursuk and others, as well as buildings associated with the new faith, such as baptisteries, basilicas, tombs and underground cemeteries in important Byzantine cities like Sfax or Daomus el-Kharita in Carthage.
Another set of photographs constitute an exceptional historical record: some show the appearance of old monuments like the basilica at Chemtou before scientific excavations were begun, while others illustrate typical excavation methods, such as those employed by Father Delattre at Carthage.
