The general agreement that in Italy the late and post-Roman period saw a widespread and marked decline in town dwelling, with various Roman centres progressively abandoned and those that survived were less populous and certainly less monumental than before, also applies for Potentia. Surviving literary sources indicate that Potentia had become an episcopal seat by the beginning of the 5th century and that a bishop was present in Potentia up to the beginning of the 6th century. Although archaeological studies still have to prove the existence of a new Christian sanctuary it should be assumed that a church was built around 400.
